     BACKGROUND 
     In oil and gas wells a primary purpose of a barrier composition such as cement or a sealant is to isolate the formation fluids between zones, also referred to as zonal isolation and zonal isolation barriers. Cement is also used to support the metal casing lining the well, and the cement provides a barrier to prevent the fluids from damaging the casing and to prevent fluid migration along the casing. 
     Typically, an oil well is drilled to a desired depth with a drill bit and mud fluid system. A metal pipe (e.g., casing, liner, etc.) is lowered into the drilled well to prevent collapse of the drilled formation. Cement is placed between the casing and formation with a primary cementing operation. One or more downhole tools may be connected to the casing to assist with placement of the cement. 
     In a primary cementing operation, a cement blend tailored for the environmental conditions of the wellbore is pumped into the wellbore. This pumping operation may utilize pumping equipment, which may include a plurality of components controlled by a controller such as valves and pumps. The plurality of components may require routine maintenance and, in some cases, repair of one or more components. Personnel may perform a diagnostic test of one or more of these components before a job, although the data generated about the operation of these components is not necessarily conclusive as to the capacity of those components to complete the intended job, nor is the data necessarily indicative of the operational condition of the equipment. Improved methods of determining the operational condition of the pumping equipment are needed.

     DETAILED DESCRIPTION 
     It should be understood at the outset that although illustrative implementations of one or more embodiments are illustrated below, the disclosed systems and methods may be implemented using any number of techniques, whether currently known or not yet in existence. The disclosure should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, but may be modified within the scope of the appended claims along with their full scope of equivalents. 
     Oil well construction can follow a series of construction stages including drilling, cementing, and completion or stimulation. Each stage can be carried out using specialized equipment and materials to complete each stage. 
     Examples of the equipment that may be used at these stages include various configurations, types, and/or sizes of pumping equipment. For example, during the drilling stage, an oil well can be drilled with a drill bit, a mud system, and a mud pump. As the drill bit penetrates the earth strata, a drilling mud is pumped down a drill string to bring cuttings back to the surface, an example of which includes a reciprocating (e.g., plunger-type) pump. The mud pumping equipment may include a mixing system for blending dry mud blend with a liquid, e.g., water, to produce a mud slurry. 
     Also, for example, during the cementing stage, a cement pump may be used to introduce a cementitious slurry, e.g., a cement composition, into the annulus formed between the casing and the wellbore. The cement typically used for cementing oil wells can be a Portland cement comprised of a hydraulic cement with a source of free lime and alkali ions, a source of calcium carbonate, a source of calcium sulfate and an organic component. The mixing system can blend the dry cement with water to produce the cement slurry. 
     In another example, during the completion and/or stimulation stage, a blender and high pressure pump may be used to fracture a formation with a proppant slurry. The blender, also referred to as a blender unit, may include a mixing system for blending proppant, e.g., sand, and water with various additives, e.g., friction reducers, to produce the proppant slurry. The high pressure pumps, also referred to as fracturing units, may deliver the proppant slurry into the wellbore with sufficient pressure to fracture the formation and deposit the proppant into the fractures. 
     The pumping equipment used at various well construction stages may include or be communicatively coupled to a unit controller. The unit controller may comprise a computer system with one or more processors, memory, input devices, and output devices. The unit controller may be programmable with one or more pumping procedures for the mixing and placement of wellbore treatments. The unit controller can be communicatively connected to various components of the pumping equipment including the mixing system and main pump. For example, the unit controller may be communicatively coupled to a mixing drum, a water pump, a plurality of valves, an additive system, a main pump, and a data acquisition system. The unit controller can establish control over the various components of the pumping equipment, e.g., the mixing system, with the data acquisition system providing feedback of the pumping operation. In some cases, the respective unit controllers associated with two or more pumping equipment assemblies may be communicatively connected so that the pumping equipment assemblies cooperatively work together. For example, the blender and one or more high pressure pumps may cooperatively deliver proppant slurry to the wellbore. 
     The delivery of the wellbore treatment, e.g., a cement slurry, from the pumping equipment at a desired flowrate can depend upon the health of the mixing system. The health of the mixing system may decline based on the accumulated volume of treatments mixed, the amount of time in operation, and/or the number of jobs performed. For example, the various components of the mixing system may encounter wear and general degradation of operating ability during normal operation from sequential jobs. Service personnel can perform diagnostic tests on the various components of the mixing system before or after a job, however, in some cases the diagnostic tests can be inconclusive and/or service personnel may not recognize data indicative of present or forthcoming problems. Additionally or alternatively, the service personnel may fail to record or submit the diagnostic test results for evaluation. As such, an improved method of determining the health status of the mixing system is needed. 
     In an embodiment, a system for automatically determining the health status of the mixing system can include an application executed via unit controller associated with a mixing system. The application can execute a diagnostic method, for example, a diagnostic test, on the mixing system by causing components of the mixing system to perform a predetermined routine while automatically logging the results. In an embodiment, the predetermined routine may comprise a flowrate test performed on the mixing system. For example, the application may cause the mixing system to perform steps that include setting a valve position, operating a pump such that a fluid is communicated through one or more components of the mixing system at one or more predetermined flowrates, and recording data from sensors during communication of the fluid. The data from the sensors can be logged into a data storage location on the unit controller and, optionally, displayed on Human Machine Interface (HMI), e.g. a display. The data can comprise pump speed value, valve position value, flowrate data, pressure data, or combinations thereof. The data may be subjected to processing to yield results indicative of the health status of the mixing system. For example, the results may indicate that the mixing system is operating nominally, that the mixing system, or a component thereof, needs maintenance, that the flowrate of a supply pump is below an operating threshold, that the mixing system cannot obtain the needed flowrates and should be taken out of service, or combinations thereof. The results may be displayed as a curve, a table, or simple pass or fail, e.g., pass/fail status, an error or warning message, or combinations thereof. 
     Additionally or alternatively, in an embodiment the unit controller can cause the data and/or results to be wirelessly communicated between the system and a remote location, for example, a remote service center. For example, in an embodiment, the unit controller may comprise or be communicatively coupled to a wireless communication assembly capable of wireless communication with the remote service center, such as through a mobile network. In some embodiments, the data can be transmitted to the remote service center for processing to yield the results indicative of the health of the mixing system. Additionally or alternatively, in some embodiments the results of the flowrate test can be transmitted to the remote location, for example, a data storage location and/or the remote service center, for recordation. The unit controller may automatically report the health status of the mixing system at the end of the test. 
       FIG.  1    illustrates a well site environment  10 , according to one or more aspects of the presently-disclosed subject matter. The well site environment  10  comprises a drilling or servicing rig  12  that extends over and around a wellbore  16  that penetrates a subterranean formation  18  for the purpose of recovering hydrocarbons. The wellbore  16  can be drilled into the subterranean formation  18  using any suitable drilling technique. While shown as extending vertically from the surface  14  in  FIG.  1   , the wellbore  16  can also be deviated, horizontal, and/or curved over at least some portions of the wellbore  16 . For example, the wellbore  16 , or a lateral wellbore portion of the wellbore  16 , can have a vertical portion  20 , a deviated portion  22 , and a horizontal portion  24 . Portions or all of the wellbore  16  can be cased, open hole, or combination thereof. For example, a first portion extending from the surface can contain a string of casing  26  and a second portion can be a wellbore drilled into a subterranean formation  28 . A primary casing string  26  can be placed in the wellbore  16  and secured at least in part by cement  30 . 
     The servicing rig  12  can be one of a drilling rig, a completion rig, a workover rig, or other structure and supports operations in the wellbore  16 . The servicing rig  12  can also comprise a derrick, or other lifting means, with a rig floor  32  through which the wellbore  16  extends downward from the servicing rig  12 . In some cases, such as in an off-shore location, the servicing rig  12  can be supported by piers extending downwards to a seabed. Alternatively, the servicing rig  12  can be supported by columns sitting on hulls and/or pontoons that are ballasted below the water surface, which can be referred to as a semi-submersible platform or floating rig. In an off-shore location, a casing can extend from the servicing rig  12  to exclude sea water and contain drilling fluid returns. 
     In an embodiment, the wellbore  16  can be completed with a cementing process by way of which a cement  30  is disposed in an annular space  40  between the casing string  26  and the wellbore  16 . A pump unit  34 , also called cement pumping equipment  34 , can be fluidically connected to a wellhead  36  by a supply line  38 . The wellhead  36  can be any type of pressure containment equipment connected to the top of the casing string  26 , such as a surface tree, production tree, subsea tree, lubricator connector, blowout preventer, or combination thereof. The wellhead  36  can anchor the casing string  26  at surface  14 . The wellhead  36  can include one or more valves to direct the fluid flow from the wellbore and one or more sensors that gather pressure, temperature, and/or flowrate data. In operation, the pump unit  34  can pump a volume of cementitious slurry, which may be specifically tailored to the wellbore, though the supply line  38 , through the wellhead  36 , down the casing string  26 , and into the annular space  40 . 
     The cement  30  can be Portland cement or a blend of Portland cement with various additives to tailor the cement for the wellbore environment. For example, retarders or accelerators can be added to the cementitious slurry to slow down or speed up the curing process. In some embodiments, the cement  30  can include a polymer designed for high temperatures. In some embodiments, the cementitious slurry can include additives such as fly ash to change the density, e.g., decrease the density, of the cementitious slurry. 
     The pump unit  34 , also referred to as a wellbore pump unit, may include mixing equipment  44 , pumping equipment  46 , and a unit controller  48 . The mixing equipment  44  can be in the form of a jet mixer, recirculating mixer, a batch mixer, a single tub mixer, or a dual tub mixer with a mixing device and a liquid delivery system. The mixing equipment  44  can combine a dry ingredient, e.g., cement, with a liquid, e.g., water, for pumping via the pumping equipment  46  into the wellbore  16 . The liquid delivery system comprises a supply pump. a flow control valve, and sensors. The pumping equipment  46  can be a centrifugal pump, piston pump, or a plunger pump. The unit controller  48  may establish control of the operation of the mixing equipment  44  and the pumping equipment  46 . The unit controller  48  can operate the mixing equipment  44  and the pumping equipment  46  via one or more commands received from the service personnel as will be described further herein. Although the pump unit  34  is illustrated as a truck, it is understood that the pump unit  34  may be skid mounted or trailer mounted. Although the pump unit  34  is illustrated as a single unit, it is understood that there may be 2, 3, 4, or any number of pump units  34  fluidically coupled to the wellhead  36 , for example, via a fluid manifold. 
     Although the embodiment of  FIG.  1    describes the well site environment  10  in the context of a cementing operation, in an additional or alternative embodiment, for example, in the context of a drilling or completion operation, a pump unit similarly-situated to the pump unit  34  of  FIG.  1    can be a mud pump fluidically connected to the wellbore  16  by the supply line  38  to pump drilling mud slurry or a water based fluid such as a completion fluid, e.g., a completion brine, into the wellbore  16 . Mixing equipment  44  may similarly be employed to blend or mix a dry mud blend with a fluid such as water or on-based fluid. The pumping equipment  46  may include a piston pump or other suitable type or configuration. The drilling mud slurry or the completion brine may be referred to as a wellbore treatment. 
     In an alternate embodiment, for example, in the context of a completion operation, a pump unit similarly situated to the pump unit  34  of  FIG.  1    can be a blender fluidically connected to one or more high pressure pumping units, also called “frac” pumps, that are fluidically connected to the wellbore  16  by the supply line  38  to pump a wellbore treatment, e.g., frac slurry, into the wellbore  16 . Mixing equipment like the mixing equipment  44  of  FIG.  1    may similarly be employed to blend or mix a proppant, e.g., sand, with a water mixture that includes one or more additives, e.g., a friction reducer or a gel, into the frac slurry. The pumping equipment  46  may be a centrifugal pump or a plunger pump. Although one pump unit  34  is illustrated in  FIG.  1   , it is understood that two or more pump units may be coupled to the wellbore  16  and communicatively coupled by the unit controller  48  to cooperatively pump a wellbore treatment into the wellbore  16 . For example, a blender may be fluidically coupled to wellhead  36  via a frac pump. The blender and the frac pump may be communicatively coupled by the unit controller  48 . 
     Referring to  FIG.  2   , a particular embodiment of the pump unit  34  is illustrated in further detail as pump unit  100 . In the embodiment of  FIG.  2   , the pump unit  100  comprises a supply tank  102 , a mixing system  120 , a main pump  106 , and at least one power supply  108 . The main pump  106  can be a centrifugal pump. The power supply  108  can include one or more electric-, gas-, or diesel-powered motors which are coupled to the supply tank  102 , the mixing system  120 , the main pump  106 , and the various components such as feed pumps and valves. The power supply  108  may supply power to actuate the main pump  106 . For example, the power supply  108  can be directly coupled by a drive shaft or indirectly coupled, such as via an electrical power supply, to the main pump  106 . The mixing system  120  can blend a fluid composition of water, dry ingredients, e.g., cement, mud, or sand, and other additives for delivery to the wellbore  16  via the main pump  106 . 
     The pump unit  100  may comprise a unit controller  140 , a data acquisition system (DAQ) card  142 , and a display  144 . The unit controller  140  may comprise a computer system comprising one or more processors, memory, input devices, and/or output devices. The unit controller  140  may have one or more applications executing in memory and configured to carry out one or more of the methods or protocols disclosed herein, or a portion thereof. The unit controller  140  may be communicatively connected to the pumping equipment and mixing equipment of the pump unit  34 . The DAQ card  142  may convert one or more analog and/or digital signals into signal data In various embodiments, the DAQ card  142  may be a standalone system with a microprocessor, memory, and one or more applications executing in memory, or may be combined or incorporated with the unit controller  140  into a unitary assembly. For example, the DAQ card  142  may be combined with one of the input output devices of the unit controller  140  when combined into a unitary assembly. The display  144 , e.g., interactive display, may be a suitable configuration of Human Machine Interface (HMI) that provides an input device and an output device for the unit controller  140 . Additional or alternative may also be used. The display  144  may include a selectable input screen that includes icons and selectable key board or key pad inputs for the unit controller  140 . The display  144  may display data and information about the status and operation of the pump unit  100  to a user, including data from the DAQ card  142 . 
     The supply tank  102  can store a volume of water or other liquid and provide the water or liquid for use in the mixing system  120 . The supply tank  102  can be connected to a water supply unit by a supply line  112 , a supply pump  114 , and a supply valve  116 . The supply pump  114  can comprise a centrifugal pump, a piston pump, or a plunger pump. The supply valve  116  can comprise a flow control valve, e.g., a globe valve, a pinch valve, or a needle valve, that can be open, closed, or regulate the fluid flow within. The unit controller  140  may provide power, e.g., voltage and current, and/or a control signal to the supply valve  116  and the supply pump  114 . The supply tank  102  may have one or more sensors, e.g., a tub level sensor, communicatively connected to the unit controller  140  via the DAQ card  142 . 
     The mixing system  120  can include the mixing drum  104 , one or more additive systems  122 , and a liquid delivery system  134 . The liquid delivery system can fluidically connect the supply tank  102  to the mixing drum  104 . The one or more additive systems  122  may fluidically connect a volume of liquid additives, such as accelerators, retarders, extenders, fluid loss, and viscosity modifiers, to the mix drum  104 . The additive systems  122  can comprise an additive pump  130 , an additive valve  132 , and flow meter. The additive pump  130  can be a diaphragm pump, a piston pump, or a centrifugal pump. The additive valve  132  can be an on-off valve such as a ball valve or plug valve. Each additive pump  130  can be communicatively coupled to a corresponding flow meter and to the unit controller  140  via the DAQ card  142 . The unit controller  140  can dispense a predetermined volume of additive by controlling the additive pump  130  and additive valve  132  with feedback from the flow meter. The liquid delivery system  134  can supply a predetermined flowrate of liquid, e.g., water, to the mix drum  104 . The unit controller  140  may change the volumetric rate of the liquid, e.g., water, with the supply pump  124  and the valve position of the flow control valve  170  in response to the data from one or more sensors, e.g., flow meter. The mixing system  120  can include a mixing valve  126  located downstream from the mixing drum  104 . The mixing valve  126  can be a flow control valve or an isolation valve, e.g., a ball valve or plug valve. 
     The liquid delivery system  134  comprises a supply pump  124  and a flow control valve  170 . The flow control valve  170  may be a globe valve, a pinch valve, a needle valve, a plug valve, or a slide valve. The supply pump  124  may be a centrifugal pump, a plunger pump, a screw pump, a piston pump, or combinations thereof. The unit controller  140  can direct the liquid delivery system  134  to pump water at a desired flowrate from the supply tank  102  to the mix drum  104  with various sensors providing feedback. In an embodiment, the liquid delivery system  134  can pump water from a supply line  112  connected to a water supply unit. 
     The main pump  106  may be configured according to the operation in which it will be employed. For example, the main pump  106  may be a centrifugal pump, a piston pump, or a plunger pump. For example, in the context of a cementing operation, the main pump  106  can be a centrifugal pump. The slurry mixed within the mixing drum  104  can be transferred to the main pump  106  via the mixing valve  126 . The main pump  106  may have a main valve  172  coupled to the outlet of the main pump  106 . The main valve  172  may be a stand-alone valve or may be a portion of a discharge manifold. A discharge manifold may have one or more flow valves and one or more isolation valves. The main valve  172  can be a flow control valve or an isolation valve such as a plug valve or ball valve. The unit controller  140  may be communicatively coupled to the main pump  106  and the main valve  172 . The unit controller  140  may control the operation of the main pump  106  to change the pump rate of the main pump  106  and the valve position of the main valve  172  in response to the data from one or more sensors, e.g., a flow meter. 
     Although the pump unit  100  of  FIG.  2    is described as a cement pumping unit, it is understood that the pump unit  100  may be a mud pump, a blender, a frac pump, or a water supply. Each type or configuration of pump unit, e.g., a mud pump, a cement pump unit, a blender, a frac pump, or a water supply, may include a main pump, e.g.,  106 , a flow control valve, e.g.,  170 , and a unit controller, e.g.,  140 . The unit controller, e.g.,  140 , may receive data via a DAQ card  142 . The unit controller  140  of the pump unit, e.g.,  100 , may be communicatively connected to one or more pump units, e.g.,  100 , at the wellsite. The pump unit, e.g.,  100 , may work in concert with at least one more pump unit, e.g.,  100 . In a scenario, the pump unit  100  may be controlled, via the unit controller  140 , by a control system at the wellsite. The pump unit  100  may be communicatively connected to a control system at the wellsite. 
     In some embodiments, a wellbore servicing method may include providing a wellbore treatment, via a pump unit, following a prescribed pumping procedure for the placement of the wellbore treatment at a target location within the wellbore. The wellbore treatment placed in the performance of the pumping procedure can include a treatment blend, e.g., cement blend, a liquid blend, e.g., water with additives, or combinations thereof and may be placed via one or more downhole tools. 
     In an embodiment, the wellbore servicing method may comprise transporting the pump unit, e.g.,  34  of  FIG.  1   , to the wellsite environment  10 . The pump unit  34  may be positioned at the wellsite and fluidly connected the wellbore  16 , for example, via a supply line  38  coupled to the wellhead  36 . 
     The liquid and/or treatment blend may be prepared within the pump unit, e.g.,  34  of  FIG.  1   , as a wellbore treatment, e.g., a cementitious slurry. The pump unit, e.g.,  34  of  FIG.  1   , can mix the treatment blend and the liquid blend within the mixing equipment, e.g.,  44  of  FIG.  1   , to form a treatment slurry and pump the treatment slurry into the wellbore  16  with the pumping equipment  46  via the supply line  38 . The pumping unit  34  can deliver the treatment slurry into the wellbore  16  at a desired flowrate per the pumping procedure. Turning back to  FIG.  2   , the flowrate of the blended slurry from the pump unit  100  to the wellbore  16  can be controlled by the unit controller  140 . The liquid delivery system  134  can transfer a liquid, e.g., water, from the supply tank  102  to the mixing drum  104  at a predetermined flowrate per the pumping procedure to create the blended slurry within the mixing system  120  for delivery to the wellbore  16  via the main pump  106 . The operational capacity of the liquid delivery system  134  to deliver fluid at a desired or predetermined flowrate can depend on the health of the mixing system  120 . 
     In an embodiment, a method of providing a wellbore treatment to a wellbore may include one or more steps effective to determine the health of the mixing system  120 . As used herein, the term “health,” when used with reference to the mixing system  120 , may refer to the ability of the liquid delivery system  134  to transfer a liquid to the mixing drum  104  for blending of the wellbore treatment in accordance with a specified operational capacity. The operational capacity of the liquid delivery system  134  can be described as the fluid output, e.g., pressure and flowrate, from the supply tank  102 , to the mix drum  104  via the supply pump  124  and flow control valve  152 . In an embodiment, the determination of the health of the mixing system  120  can comprise a determination that the mixing equipment  120  attains an operational capacity in accordance with the needs of a current or anticipated pumping operation and/or a determination that the mixing equipment  120  attains at least a minimum operational capacity. In an embodiment, the minimum operational capacity of the liquid delivery system  134  may be the minimum rated capacity, e.g., pressure and flowrate, of the supply pump  124 , when operating optimally, at a given pump speed measured in revolutions per minute (RPM). As will be appreciated by those of skill in the art upon viewing this disclosure, the supply pump  124 , when new or newly-refurbished, may attain optimal performance, such as the rated pump capacity. However, the performance, e.g., output, of the supply pump  124  may decrease due to damage from wear, erosion, material degradation, and/or failure of one or more pump components such as seals, bearings, valves, or impellers. 
     As will be appreciated by those of skill in the art upon viewing this disclosure, a current or anticipated pumping operation may require that the mixing equipment be able to provide certain operational performance values, e.g., a combined pressure and flowrate, less than the minimum operational capacity of the mixing equipment. However, a change in wellbore conditions may require the mixing equipment  120  to perform at a higher operational performance value that may include the minimum operational capacity. As such, it is important to understand the operational capacity of the liquid delivery system  134  prior to beginning a wellbore servicing operation at a wellsite. 
     In an embodiment, a diagnostic test to determine the health status of the mixing system  120  may be automatically performed prior to the initiation of a wellbore servicing operation, at the completion of a wellbore servicing operation, or both. For example, the diagnostic test may be included in a startup procedure for the pumping unit  100 , a shutdown procedure for the pumping equipment, or both. When the diagnostic test is to be performed, the unit controller  140  may automatically initiate the diagnostic test or may prompt a user, e.g., service personnel, to initiate the diagnostic test. In an embodiment, the pumping unit may be prohibited from completing a startup or shutdown procedure where the diagnostic test is not completed, for example, such that the pumping unit cannot be used in the performance of a wellbore servicing operation until the diagnostic test is completed. 
     In an embodiment, the results of the diagnostic test can be outputted, for example, as an alert provided to the service personnel, for example, a pass/fail indicia, a text message, or combination. For example, in an embodiment, the service personnel may be notified of a “fail” status, which may be the result of the diagnostic test. Additionally or alternatively, the fail status may be the result of a missing system performance file including the results of the diagnostic test, a corrupted system performance file, or a system performance file that cannot be accessed. In various embodiments, the alert provided to the service personnel may be generated by the unit controller  140 , a remote computer, e.g., executing on a network location, or a combination thereof as will be disclosed further hereinafter. Additionally or alternatively, the results of the diagnostic test may form the basis for an action. For example, where a pumping unit  100  has been assigned a fail status, the unit controller  140  may prohibit operation of the pumping unit  100  until the diagnostic test has been performed and the pumping unit is assigned a pass status, until the pumping unit is serviced, or the like. 
     In an embodiment, a method for determining a health status of the mixing system  120  may generally include the steps of preparing the mixing system  120  for a diagnostic test, running the diagnostic test and collecting a plurality of periodic datasets, assessing the plurality of periodic datasets, and determining health of the mixing system  120  based upon the results of assessing the dataset. 
     In an embodiment, the mixing system  120  may be prepared for the diagnostic test by configuring the mixing system  120  a flow loop through at least a portion of the mixing system  120 . For example, turning now to  FIG.  3   , an example of a flow loop  150  is described. For example, in some embodiments, the unit controller  140  may control the pump unit  100  components, e.g., one or more components of the pump unit  100 , so as to establish the flow loop  150  by causing one or more valves to be opened or closed. For example, as shown in  FIG.  3   , the unit controller  140  can cause the mixing valve  126 , the supply valve  116 , and the plurality of additive valves  132  of the additive systems  122  to be closed, and by causing an isolation valve  168  on a return line  162  from the mixing drum  104  and the supply tank  102  and a flow control valve  152  on the supply line  158  from the supply tank  102  to the mixing drum  104  to be opened. The return line  162  and the supply line  158  may include a portion of a larger manifold system of the pump unit  100 . It is understood that in  FIG.  3    the location of the supply line  158  and location of the return ne  162  are illustrated for clarity and may not represent the actual, physical location of such components. For example, the return line  162  may be located adjacent of the supply line  158  or vice versa. Also, although one valve is shown in the return line  162  and the supply line  158 , it is understood that the return line  162  and the supply line  158  can include 1, 2, 3, or any number of valves. The flow loop  150  includes some of the same components previously described in  FIG.  2    and are labeled the same. For example, the flow loop  150  comprises the supply tank  102 , the supply line  158 , the supply pump  124 , the flow control valve  152 , the mix drum  104 , the return line  162 , and the isolation valve  168 . The supply line  158  can include a flowrate sensor  156 , a first pressure sensor  164 , and a second pressure sensor  166  communicatively connected to the unit controller  140 . The valve actuator  154  can be mechanically connected to the flow control valve  152  and communicatively connected to the unit controller  140 . The flow control valve  152 , the valve actuator  154 , or combinations thereof may include one or more valve position sensors communicatively connected to the unit controller  140 . The flow ate sensor  156  may comprise a turbine type or Coriolis type flow meter. 
     Also, in some embodiments, the mixing system  120  may be prepared for the diagnostic test by filling or otherwise providing fluid to the flow loop  150 . For example, the unit controller  140  may control pump unit  100  components to fill the flog loop  150  by placing water in the supply tank  102  and/or the mixing drum  104  via the supply line  112 . For example, the unit controller  140  may open the supply valve  116  and operate the supply pump  114  to fill the supply tank  102  and the mixing drum  104  until the tub level sensor in one or both locations indicates the supply tank  102  or mixing drum  104  is sufficiently filled with water. For example, the unit controller  140  may fill the supply tank  102  and mixing drum  104  until at least one tub level sensors indicates that one or both tanks are 40%, 45%, 50%, 55%, 60% or any portion of water between 15% and 100% of the filled capacity of the tubs. The unit controller  140  may stop the supply pump  114  and close the supply valve  116  such that the flow loop  150  configuration illustrated in  FIG.  3    is established or reestablished. 
     In some embodiments, running the diagnostic test may include operating the mixing system  120  to circulate a fluid, e.g., water, through the flow loop  150  at a plurality of flowrates and/or pressures to produce the plurality of periodic datasets, which generally includes data indicative of the performance of the mixing system  120  or components thereof. In various embodiments, any suitable protocol suitable to generate the plurality of periodic datasets may be employed, although an example of a protocol is disclosed herein. 
     For example, the unit controller  140  may control pump unit  100  components so as to determine the maximum flowrate of the flow loop  150 . The unit controller  140  may position the flow control valve  152  to a first position, for example, a fully open position, e.g., 100% open, and operate the supply pump  124  at a first flow capacity of 100% flow capacity, e.g., the rated pump capacity at the rated pump speed of the supply pump  124 . The water may travel through the flow loop  150  in a continuous path from the supply tank  102 , into the supply line  158 , through the supply pump  124 , the flowrate sensor  156 , the flow control valve  152 , the mixing drum  104 , into the return line  162 , through the isolation valve  168 , and back into the supply tank  102 . The supply line  158  and the return line  162  may be disposed at approximately the same height to minimize the pressure loss and/or pressure differentials due to the path of the flow loop  150 . As the fluid is communicated via the flow loop  150 , the unit controller  140  may monitor flowrate data from the flowrate sensor  156  for a predetermined time period, e.g., 60 seconds, or until the data from the flowrate sensor is steady-state. The unit controller  140  may record and save a periodic dataset comprising the pump speed (RPM), and a set of data for a predetermined period of time for the flowrate sensor, valve position sensor, at least one pressure sensor, at least one tub level sensor, or combination thereof for a predetermined period of time. 
     Additionally, the unit controller  140  may also control pump unit  100  components so as to determine a plurality of data points for the supply pump  124  operating at 100% of the rated pump speed, e.g., 100% flow capacity, with the valve position set to a plurality of positions. For example, the unit controller  140  may change the valve position and generate a second periodic dataset. For example, the unit controller  140  may change the valve position of the flow control valve  152  to second position, e.g., 75% open, while maintaining the operation of the supply pump  124  at 100% pump speed. The unit controller  140  may again record and save the second periodic dataset. The unit controller  140  may also change the valve position to a third position, a fourth position, or a plurality of predetermined positions. For example, the valve positions may include 100% open, 75% open, 50% open, 25% open, and 0% open. Although five (5) positions are listed in this example, it is understood that the unit controller  140  could control the pump unit components to likewise utilize 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or any number of valve positions. Likewise, although particular valve positions are given as an example, the unit controller  140  could specify 100% open, 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20%, 10%, 0% open, or any valve position value within the range of 0% to 100%. The unit controller  140  may also record and save a periodic dataset for each valve position, for example, to a system performance file in memory. 
     Additionally, the unit controller  140  may change the operation of the supply pump  124  to a second pump speed, such as 50% of the rated pump speed, that corresponds to a second flow capacity, e.g. 50% flow capacity. The unit controller  140  can record and save a periodic dataset for the first valve position at the second flow capacity, change to the valve position to a second valve position, record and save a periodic dataset for the second valve position for the second flow capacity, and repeat for a plurality of valve positions for the second flow capacity. 
     The unit controller  140  may operate the supply pump  124  at a plurality of pump speeds that correspond to a plurality of flow capacities. For example, the unit controller  140  may operate the pump at 25%, 50%, 75%, and/or 100% of a rated pump speed, which may correspond to 25%, 50%, 75%, and/or 100% flow capacity. Although 4 pump capacity values are listed, it is understood that the unit controller  140  may operate the pump at 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or any capacity value within the range of 10% to 100%. The unit controller  140  may determine a periodic dataset for each of a plurality of pump flow capacities and at a plurality of valve positions at each pump flow capacity value. For example, the unit controller  140  may determine 15 periodic datasets for valve positions 100% open, 75% open, 50% open, 25% open, and 0% open of the flow control valve  152  and for the 50%, 75%, and 100% flow capacity of the supply pump  124 . The plurality of periodic datasets can be written to the system performance file in a location in memory. The plurality of periodic datasets may be stored as a text string, a database, or combination thereof. 
     In some embodiments, the system performance file may include identifying indicia, for example, a unique serial number, capable of uniquely identifying the unit controller  140 , the pump unit  100 , and/or one or more components of the pump unit  100 . 
     In some embodiments, assessing the plurality of periodic datasets may comprise subjecting at least a portion of the plurality of periodic datasets to one or more processing and/or evaluation techniques. For example, in some embodiments, the processing may include the application of one or more data reduction techniques to smooth the periodic set of data. The data reduction techniques may include data pre-processing, data cleansing, numerosity reduction, or a combination thereof. The data pre-processing technique may remove out-of-range values and/or flag missing values within the dataset. The data cleansing process(es) may include the use of statistical methods, data duplicate-elimination methods, and the parsing of data for the removal of corrupt or inaccurate data points. In some embodiments, the post-processing periodic dataset may be saved to the system performance file. 
     In some embodiments the post-processing periodic dataset may be averaged to produce an average value representative of each set of periodic data. The average value may be a single value that represents a plurality of values across a given duration. The average value may be determined by applying one or more mathematical techniques such as an arithmetic mean, a median, a geometric median, a mode, a geometric mean, a harmonic mean, a generalized mean, a moving average, or combinations thereof. The unit controller  140  may save the average value to the system performance file. In some embodiments, the average value may be determined as each of the plurality of periodic datasets is generated, for example, in real-time or, alternatively, at a later time. 
     In some embodiments, the assessing, post-processing, and averaging of the plurality of the periodic datasets may include one or more “Edge Computing” locations. For example, the unit controller  140  may transmit the system performance file to a network location via a mobile communication network for processing of the periodic datasets. The unit controller  140  may retrieve or receive the system performance file post-processing. 
     In some embodiments, assessing the plurality of periodic datasets may further comprise determining one or more functions, e.g., mathematical functions, representative of each of the plurality of periodic datasets. For example, in an embodiment, a function may be determined as discussed with respect to  FIG.  4   .  FIG.  4    illustrates an example of a system performance graph  300 . In an embodiment, the system performance graph  300  illustrates flowrate with respect to valve position, for example, having a y-axis  302  with flowrate units and an x-axis  304  with valve position units. For example, the y-axis  302  may display the flowrate data with units of volumetric flowrate such as gallons per minute (GPM) or barrels per hour (BPH). The x-axis  304  may display the valve position data as a percentage of the opening value of the valve position, such as 50% open or 100% open. The graph of the system performance graph  300  may comprise a curve for each pump speed, such as 100% 75%, and 50% of pump speed. In the embodiment of  FIG.  4   , a first curve  310 , e.g., system performance curve, may be for a pump speed of the supply pump  124  of 100%. A second curve  312 , e.g., system performance curve, may be for a pump speed of the supply pump  124  of 75%. A third curve  314 , e.g., system performance curve, may be for a flow capacity of the supply pump  124  of 50%. Although three system performance curves are illustrated, it is understood that there may be a system performance curve for each pump speed. A first line  322  may represent a valve position of 100% open. A second line  326  may represent a valve position of 50% open. The minimum data point on the first curve  310  may be at the origin of the system performance graph  300  where the valve position is 0% open or also referred to as dosed. The maximum data point on the first curve  310  may be at data point  324  where the valve position is 100% open and the pump is operating with pump speed of 100%. The average data points may be displayed on the system performance graph  300 . For example, average data point  332  on the first curve  310  may coincide with the second line  326  from the x-axis  304  for the valve position of 50% open and the pump operating with a pump speed of 100%. 
     A system mathematical function may be determined that best fits each the plurality of average values for each pump speed. An example of a mathematical function can be; y=Ax 2 +Bx+C. The mathematical function may be determined using mathematical techniques of interpolation or data smoothing to obtain the best fit of the dataset. The mathematical equation can be a function of the y-axis  302  where value of the y-axis  302  is a flowrate value dependent on the value of the x-axis  304 , i.e., the value of the valve position. The value for C in the example mathematical function may be a zero value when the minimum value of the equation coincides with the origin, e.g., point  320 . Although the mathematical function in the example is a polynomial equation, it is understood that the mathematical function may be polynomial, logarithmic, exponential, or combination thereof. At least one system mathematical function may be recorded and saved to the system performance file. In some embodiments, the unit controller  140  may cause at least one of the curves and/or a system mathematical function to be displayed on the interactive display  144 . In some embodiments, the determination of one or more system mathematical functions may be processed by one or more “Edge Computing” locations. For example, the unit controller  140  may transmit the system performance file to a network location via a mobile communication network for processing of the system mathematical functions. The unit controller  140  may retrieve or receive the system performance file post-processing. 
     In an embodiment, assessing the plurality of periodic datasets may further comprise interpolating a value for a valve position on the x-axis  304 . In an example, the first curve  310  may have a known data point  332 . The data point  332  may be a flowrate value  334  at a valve position value, e.g., 50% open, as shown by the second line  326  and may lie along or proximate to the first curve  310  for the pump operating at 100% pump speed, e.g., 100% capacity. The unit controller  140  may determine an equivalent value  330  on the second curve  312  for the pump operating at 75% pump speed. A third line  336  representing the valve position value for the equivalent value  330  on the second curve  312  for the flowrate value  334  may be interpolated, for example, by a suitable method of mathematical interpolation such as linear interpolation, polynomial interpolation, spline interpolation, or a combination thereof. The system mathematical function may be solved for the second curve  312  for the flowrate value  334  by iteratively substituting a valve position value until the calculated flowrate value is within a threshold value of the flowrate value  334 . The unit controller  140  may write the calculated point, also called the equivalent value  330 , to the system performance file. 
     In an embodiment, the health of the mixing system  120  can be determined based on the results of the diagnostic test. In some embodiments, the results of the diagnostic test may comprise one or more averaged values, a plurality of averaged values, a system performance curve, a system mathematical function, or combination thereof. In an example, the results of the diagnostic test can be compared to the minimum operational capacity for the mixing system  120 . Additionally or alternatively, the results of the diagnostic test can be compared to maintained operational capacity, for example, an expected capacity based upon prior use and maintenance of the mixing system. Additionally or alternatively, the results of the diagnostic test can be compared a historical database, for example, a capacity based upon historical data from multiple mixing systems and components. 
     In various embodiments, the results of the diagnostic test may be compared to an operational indicator set, which may comprise a configuration check, the minimum operational capacity, a nominal operational capacity, a series of failure modes, or combinations thereof. 
     In an embodiment, the nominal operational capacity can comprise one or more values indicative of the normal operational capacity of a well-maintained or recently-serviced portion of the pump unit  100 , e.g., the mixing system  120 . A values of the nominal operational capacity, e.g., system performance curve, can be indicative of the nominal operational capacity of the mixing system  120  comprising the supply pump  124  and the flow control valve  152  of the liquid delivery system  134 . 
     In an embodiment, the failure modes may comprise one or more values indicative of one or more failure modes, e.g., bearing failure, of the mixing system  120 . The values of the failure modes can be indicative of one or more failures of the mixing system  120  or a component thereof. For example, failure of the supply pump  124  to achieve a pressure value during the diagnostic test may be indicative of an imminent seal failure. 
     In an embodiment, the configuration check of the operational indicator set can comprise one or more values indicative of a proper configuration of the mixing system  120 . 
     The results from the comparison between the results of the diagnostic test and the operational indicator set may yield a status for the mixing system  120 . For example, where the system performance file meets or exceeds the values of the configuration check, the mixing system  120  may have a “passing” or “acceptable” status; where it does not, the mixing system may have a “failing” or unacceptable status. Additionally or alternatively, where the system performance file meets or exceeds the values of the minimum operational capacity, check, the mixing system  120  may have a “passing” or “acceptable” status; where it does not, the mixing system may have a “failing” or unacceptable status. Additionally or alternatively, where the system performance file meets or exceeds the values of the nominal operational capacity, check, the mixing system  120  may have a “passing” or “acceptable” status; where it does not, the mixing system may have a “failing” or unacceptable status. Additionally or alternatively, where the system performance file meets or exceeds the series of failure modes, the mixing system  120  may have a “passing” or “acceptable” status; where it does not, the mixing system may have a “failing” or unacceptable status. 
     In some embodiments, the method for determining health of the mixing system  120  may further comprise the step of creating one or more outputs responsive to the status of the mixing system  120 . 
     In various embodiments, the output may comprise indicia of the health of the mixing system, for example, a visual cue (e.g., an indicator light), textual information or messages indicating the mixing system  120  status, an audible cue such as an alarm or a buzzer, or combinations thereof. 
     For example, referring again to  FIG.  2   , the unit controller  140  may display an alert on the interactive display  144 . The alert may be displayed on the interactive display  144  as a curve, a table, or a simple pass or fail, e.g., pass/fail status. For example, a pass/fail status may be a color indicator including a green color for a passing status while a failing status can be a red color. A pass/fail status can include a multiple color indicator to indicate a range such as green, yellow, and red. The yellow can be a warning of a bottom of the range value. A pass/fail message, e.g., text message, may be included when the result is a fail. 
     In some embodiments, one or more of the steps of assessing the plurality of periodic datasets, determining the health of the mixing system, and creating one or more outputs responsive to the status of the mixing system may be carried out via the operation of the unit controller  140 . 
     A unit controller, for example, the unit controller  48  of  FIG.  1    or the unit controller  140  of  FIG.  2   , may be a computer system suitable for communication and control of various components of the pumping unit. An embodiment a unit controller, for example, the unit controller  48  of  FIG.  1    or the unit controller  140  of  FIG.  2   , is illustrated in  FIG.  5    as a computer system  176 . In the embodiment of  FIG.  5   , the computer system  176  includes one or more processors  178  (which may be referred to as a central processor unit or CPU) that is in communication with memory  180 , secondary storage  182 , input output devices  184 , DAQ card  192 , and network devices  188 . The computer system  176  may continuously monitor the state of the input devices and change the state of the output devices based on a plurality of programmed instructions. The programming instructions may comprise one or more applications retrieved from memory  180  for executing by the processor  178  in non-transitory memory within memory  180 . The input output devices may comprise a HMI, e.g., interactive display  144  in  FIG.  2   , with a display screen and/or the ability to receive conventional inputs from the service personnel such as push button, touch screen, keyboard, mouse, or any other such device or element that a service personnel may utilize to input a command to the computer system  176 . The secondary storage  182  may comprise a solid state memory, a hard drive, or any other type of memory suitable for data storage. The secondary storage  182  may comprise removable memory storage devices such as solid state memory or removable memory media such as magnetic media and optical media, i.e., CD disks. The computer system  176  can communicate with various networks with the network devices  188  comprising wired networks, e.g., Ethernet or fiber optic communication, and short range wireless networks such as Wi-Fi (i.e., IEEE 802.11), Bluetooth, or other low power wireless signals such as ZigBee. Z-Wave, 6LoWPan, Thread, and WiFi-ah. The computer system  176  may include a long range radio transceiver  190  for communicating with mobile network providers as will be disclosed further herein. 
     The computer system  176  may comprise a DAQ card  192  for communication with one or more sensors. The DAQ card  192  may be a standalone system with a microprocessor, memory, and one or more applications executing in memory. The DAQ card  192 , as illustrated, may be a card or a device within the computer system  176 . In an embodiment, the DAQ card  192  may be combined with the input output device  184 . The DAQ card  192  may receive one or more analog inputs  194 , one or more frequency inputs  196 , and one or more Modbus inputs  198 . For example, the analog input  194  may include a tub level sensor. For example, the frequency input  196  may include a flow meter, i.e.,  156  from  FIG.  3   . For example, the Modbus input  198  may include a pressure transducer, i.e.,  164  from  FIG.  3   . The DAQ card  192  may convert the signals received via the analog input  194 , the frequency input  196 , and the Modbus input  198  into the corresponding sensor data. For example, the DAQ card  192  may convert a frequency input  196  from the flowrate sensor  156  shown in  FIG.  3    into flow rate data measured in gallons per minute (GPM). 
     Additionally or alternatively, in an embodiment, one or more of the steps of assessing the plurality of periodic datasets, determining the health of the mixing system, and/or creating one or more outputs responsive to the status of the mixing system may be carried out via the operation of a computer located at a remote location, for example, a remote service center. Additionally or alternatively, in an embodiment, one or more of the steps of assessing the plurality of periodic datasets, determining the health of the mixing system, and/or creating one or more outputs responsive to the status of the mixing system may be carried out cooperatively via the operation of the unit controller  140  and a computer located at the remote location, for example, the remote service center. For example, in an embodiment, the unit controller  140  may transmit data from the diagnostic test, e.g., the system performance file, to a remote service center as will be described further therein, for example, via a data communication center. 
     For example, data can be transmitted, via a data communication system, and received by various wired or wireless means between the pump unit  100  at a wellsite and a remote service center and for further processing. Referring to  FIG.  6   , a data communication system  200  is described. The data communication system  200  comprises a pump unit  204  disposed at a wellsite  202 , an access node  210  (e.g., cellular site), a mobile carrier network  254 , a network  234 , a storage computer  236 , a service center  238 , and a plurality of user devices  252 . The pump unit  204  can include a communication device  206  (e.g., transceiver  190  of  FIG.  5   ) that can transmit and/or receive via any suitable communication means (wired or wireless), for example, to wirelessly connect to an access node  210  to transmit data (e.g., the system performance file) to a storage computer  236 . The storage computer  236  may also be referred to as a data server, data storage server, or remote server. The storage computer  236  may include a database, which may be used to store system performance files and/or diagnostic test results. Wireless communication can include various types of radio communication, including cellular, satellite  230 , or any other form of long range radio communication. The communication device  206  can transmit data via wired connection for a portion or the entire way to the storage computer  236 . The communication device  206  may communicate over a combination of wireless and wired communication. For example, communication device  206  may wirelessly connect to access node  210  that is communicatively connected to a network  234  via a mobile carrier network  254 . 
     In an embodiment, the communication device  206  on the pump unit  204  is communicatively connected to the mobile carrier network  254  that may comprise the access node  210 , a 5G edge site  212 , a 5G core network  220 , and the network  234 . The communication device  206  may be the transceiver  190  connected to the computer system  176  of  FIG.  5   . The computer system  176  may be the unit controller  140  of  FIG.  2    or unit controller  48  of  FIG.  1    thus the communication device  206  may be communicatively connected to the unit controller  140  and/or  48 . 
     The access node  210  may also be referred to as a cellular site, cell tower, cell site, or, with 5G technology, a gigabit Node B.

Turning now to  FIG.  6   , a representative example of a network slice  218  and/or  226  is described. A computing service executing on network slice  218  and/or  226  can comprise a first virtual network function (VNF)  258 , a second VNF  260 , and an unallocated portion  262 .

     Turning now to  FIG.  8 A , an embodiment of a communication system  550  is described suitable for implementing one or more embodiments disclosed herein, for example implementing communications messaging as disclosed herein including without limitation, wireless communication between the communication device  206  and the mobile carrier network  254  on  FIG.  6   ; communications with the computing components and network associated with  FIG.  5    (e.g., long range radio transceiver  190 ); and the like. Typically, the communication system  550  includes a number of access nodes, a first access node  554   a , a second access node  554   b , and a third access node  554   c  (collectively, access nodes  554 ) that are configured to provide coverage in which a plurality of user equipment (UEs)  552  such as cell phones, tablet computers, machine-type-communication devices, unit controllers, tracking devices, embedded wireless modules, and/or other wirelessly equipped communication devices (whether or not user operated), can operate. The access nodes  554  may be said to establish an access network  556 . The access network  556  may be referred to as a radio access network (RAN) in some contexts. In a 5G technology generation an access node  554  may be referred to as a gigabit Node B (gNB). In 4G technology (e.g., long term evolution (LTE) technology) an access node  554  may be referred to as an enhanced Node B (eNB). In 3G technology (.e.g, code division multiple access (CDMA) and global system for mobile communication (GSM)) an access node  554  may be referred to as a base transceiver station (BTS) combined with a basic station controller (BSC). In some contexts, the access node  554  may be referred to as a cell site or a cell tower. In some implementations, a picocell may provide some of the functionality of an access node  554 , albeit with a constrained coverage area. Each of these different embodiments of an access node  554  may be considered to provide roughly similar functions in the different technology generations. 
     It is understood that the access network  556  may include any number of access nodes  554 . Further, each access node  554  could be coupled with a core network  558  that provides connectivity with various application servers  559  and/or a network  560 . In an embodiment, at least some of the application servers  559  may be located close to the network edge (e.g., geographically close to the UE  552  and the end user) to deliver so-called “edge computing.” The network  560  may be one or more private networks, one or more public networks, or a combination thereof. The network  560  may comprise the public switched telephone network (PSTN). The network  560  may comprise the Internet. With this arrangement, a UE  552  within coverage of the access network  556  could engage in air-interface communication with an access node  554  and could thereby communicate via the access node  554  with various application servers and other entities. 
     The communication system  550  could operate in accordance with a particular radio access technology (RAT), with communications from an access node  554  to UEs  552  defining a downlink or forward link and communications from the UEs  552  to the access node  554  defining an uplink or reverse link. Over the years, the industry has developed various generations of RATs, in a continuous effort to increase available data rate and quality of service for end users. These generations have ranged from “1G,” which used simple analog frequency modulation to facilitate basic voice-call service, to “4G”—such as Long Term Evolution (LTE), which now facilitates mobile broadband service using technologies such as orthogonal frequency division multiplexing (OFDM) and multiple input multiple output (MIMO). 
     Turning now to  FIG.  8 B , further details of the core network  558  are described. In an embodiment, the core network  558  is a 5G core network. 5G core network technology is based on a service based architecture paradigm. Rather than constructing the 5G core network as a series of special purpose communication nodes (e.g., an HSS node, a MME node, etc.) running on dedicated server computers, the 5G core network is provided as a set of services or network functions. These services or network functions can be executed on virtual servers in a cloud computing environment which supports dynamic scaling and avoidance of long-term capital expenditures (fees for use may substitute for capital expenditures). These network functions can include, for example, a user plane function (UPF)  579 , an authentication server function (AUSF)  575 , an access and mobility management function (AMF)  576 , a session management function (SMF)  577 , a network exposure function (NEF)  570 , a network repository function (NRF)  571 , a policy control function (PCF)  572 , a unified data management (UDM)  573 , a network slice selection function (NSSF)  574 , and other network functions. The network functions may be referred to as virtual network functions (VNFs) in some contexts. 
     Network functions may be formed by a combination of small pieces of software called microservices. Some microservices can be re-used in composing different network functions, thereby leveraging the utility of such microservices. Network functions may offer services to other network functions by extending application programming interfaces (APIs) to those other network functions that call their services via the APIs. The 5G core network  558  may be segregated into a user plane  580  and a control plane  582 , thereby promoting independent scalability, evolution, and flexible deployment. 
     The NEF  570  securely exposes the services and capabilities provided by network functions. The NRF  571  supports service registration by network functions and discovery of network functions by other network functions. The PCF  572  supports policy control decisions and flow based charging control. The UDM  573  manages network user data and can be paired with a user data repository (UDR) that stores user data such as customer profile information, customer authentication number, and encryption keys for the information. An application function  592 , which may be located outside of the core network  558 , exposes the application layer for interacting with the core network  558 . In an embodiment, the application function  592  may be execute on an application server  559  located geographically proximate to the UE  552  in an “edge computing” deployment mode. The core network  558  can provide a network slice to a subscriber, for example an enterprise customer, that is composed of a plurality of 5G network functions that are configured to provide customized communication service for that subscriber, for example to provide communication service in accordance with communication policies defined by the customer. The NSSF  574  can help the AMF  576  to select the network slice instance (NSI) for use with the UE  552 . 
     The systems and methods disclosed herein may be advantageously employed in the context of wellbore servicing operations, particularly, in relation to the usage of wellbore servicing equipment as disclosed herein. 
     In an embodiment, the diagnostic test disclosed herein may identify equipment failures or decreases in operability that might not otherwise be identifiable. For example, a reduction in pump output of a pump (e.g., the supply pump  124 ) may be gradual and difficult to quantify or identify. The diagnostic test disclosed herein, in which a partly closed flow control valve  152  can increase the head pressure while decreasing the flowrate of the supply pump  124  can impart additional stress and can reveal a decrease in the pump output and thus a decrease in the operational capacity of the liquid delivery system  134 . 
     Additionally or alternatively, the diagnostic test disclosed herein may be automatically performed prior to the initiation of a wellbore servicing operation, at the completion of a wellbore servicing operation, or both. The unit controller  140  may automatically initiate the diagnostic test upon startup or shutdown of the pumping unit  100 , or may prompt the service personnel to initiate the diagnostic test. The unit controller  140  may prevent operation of the pumping unit  100  until the diagnostic test is completed. 
     Additionally or alternatively, the diagnostic test disclosed herein may determine if the pumping unit  100  can complete a wellbore servicing operation without interruption. The diagnostic test can determine if one or more components of the mixing system  120  can operate within operational limits of pumping unit  100 . Additionally, the diagnostic test can determine if one or more components of the mixing system  120  has decreased in operational capacity below a threshold value.
