A method for controlling a rheological state of a dispensed pressurized fluid, the method comprising: (a) selecting a pressurized fluid including a known fluid at a known pressure; (b) selecting a desired rheological state which the selected pressurized fluid exhibits when dispensed; (c) receiving the selected pressurized fluid in a first rheological state and an initial flow rate with a porous element (204, 304, 404, 504, 604) having a known pore size, a known diameter, and a known length; (d) modulating the received pressurized fluid with the porous element (204, 304, 404, 504, 604) to reduce the pressure of the pressurized fluid exiting the porous element (204, 304, 404, 504, 604) and to reduce the initial flow rate of the pressurized fluid; (e) receiving the pressurized fluid at the reduced flow rate at a proximal end of an exit tube (205, 305, 405, 505, 705) having a known inside diameter and a known length; (f) transitioning the first rheological state of the received pressurized fluid into a second rheological state of the received pressurized fluid at a distal end of the exit tube (205, 305, 405, 505, 705); and (g) dispensing the received flowed pressurized fluid at a distal end of the exit tube (205, 305, 405, 505, 705) in a desired second rheological state and reduced flow rate; (h) selecting an alternative porous element (204, 304, 404, 504, 604) with at least one selected from the group of an alternative pore size different from the known pore size, an alternative diameter different from the known diameter (width), and an alternative length different from the known length; (i) receiving the selected pressurized fluid in the first rheological state and the initial flow rate with the alternative porous element (204, 304, 404, 504, 604) when modulating the received pressurized fluid in step (d) results in an undesirable reduced flow rate or an undesirable second rheological state; and (j) repeating steps (d) - (g) using the alternative porous element (204, 304, 404, 504, 604); (k) selecting an alternative exit tube (205, 305, 405, 505, 705) wherein the alternative exit tube (205, 305, 405, 505, 705) includes at least one selected from the group of an alternative inside diameter and an alternative length, and receiving the pressurized fluid at a proximal end of the alternative exit tube (205, 305, 405, 505, 705) when dispensing the received pressurized fluid in step (g) results in a second rheological state different than the desired second rheological state; and (l) repeating steps (e) - (g) using the alternative exit tube (205, 305, 405, 505, 705). (a) selecting a pressurized fluid including a known fluid at a known pressure; (b) selecting a desired rheological state which the selected pressurized fluid exhibits when dispensed; (c) receiving the selected pressurized fluid in a first rheological state and an initial flow rate with a porous element (204, 304, 404, 504, 604) having a known pore size, a known diameter, and a known length; (d) modulating the received pressurized fluid with the porous element (204, 304, 404, 504, 604) to reduce the pressure of the pressurized fluid exiting the porous element (204, 304, 404, 504, 604) and to reduce the initial flow rate of the pressurized fluid; (e) receiving the pressurized fluid at the reduced flow rate at a proximal end of an exit tube (205, 305, 405, 505, 705) having a known inside diameter and a known length; (f) transitioning the first rheological state of the received pressurized fluid into a second rheological state of the received pressurized fluid at a distal end of the exit tube (205, 305, 405, 505, 705); and (g) dispensing the received flowed pressurized fluid at a distal end of the exit tube (205, 305, 405, 505, 705) in a desired second rheological state and reduced flow rate; (h) selecting an alternative porous element (204, 304, 404, 504, 604) with at least one selected from the group of an alternative pore size different from the known pore size, an alternative diameter different from the known diameter (width), and an alternative length different from the known length; (i) receiving the selected pressurized fluid in the first rheological state and the initial flow rate with the alternative porous element (204, 304, 404, 504, 604) when modulating the received pressurized fluid in step (d) results in an undesirable reduced flow rate or an undesirable second rheological state; and (j) repeating steps (d) - (g) using the alternative porous element (204, 304, 404, 504, 604); (k) selecting an alternative exit tube (205, 305, 405, 505, 705) wherein the alternative exit tube (205, 305, 405, 505, 705) includes at least one selected from the group of an alternative inside diameter and an alternative length, and receiving the pressurized fluid at a proximal end of the alternative exit tube (205, 305, 405, 505, 705) when dispensing the received pressurized fluid in step (g) results in a second rheological state different than the desired second rheological state; and (l) repeating steps (e) - (g) using the alternative exit tube (205, 305, 405, 505, 705).
