Viscosity
* Most viscosity depends on forces
  - intermolecular forces
  - shear forces
* Some viscosities increase with a lower temperature, some with a higher temperature
  - viscosity increases pressure.
  * is used as a way to predict when volcanoes erupt. This is because the lava has a hard time getting out and may burst out when it can
* Viscosities are comparable to petroleum-based fluids
  - can run from water thin to paste thick
* Viscosities range from paste to liquid
  - thinner than water to thicker than paste
* affects heat generation in bearings, cylinders and gears due to internal fluid friction.
* also acts internally on the fluid between slower and faster moving adjacent layers
  - depends upon the nature of the materials used in the composition of the glaze
  - refers to internal resistance experienced by the fluid before it can flow
* basically means the mobility of something.
* becomes normal by stirring.
* can also be a drawback when it comes to magnetically driven electric units.
* cans have effects.
* causes the stillness of disinclination, velocity causes the stillness of fascination
  - xenon to resist the oscillator's motion
* changes with concentration of cacao pod gum and gum karaya at different spindle speeds.
* controls the fill pressure.
* decreases because the starch molecules become shorter due to hydrolytic effects.
* denotes opposition to flow.
* depends on factors
  - temperature of both air and water, but in opposite directions
* depends on the attractive force between the molecules
  - chemical composition of the glass
* describes the thickness or resistance to flow of a contrast agent.
* determines a liquid's resistance to flow.
* flattens the effervescence of panic.
* has the dimensions mass per length per time.
* increases as temperature increases.
* increases with increasing silica content due to silica chain
  - the length of the boiling time
* influences the spray pattern when the fuel is injected into the cylinder.
* is absolutely critical to inkjet printing
  - also an important characteristic of a lubricant
* is an important property in determining the eruptive behavior of magmas
  - of drilling fluids
  - subject in chemistry and chemical engineering
  - internal property of a fluid that offers resistance to flow
  - associated with the ability of a fluid to flow freely
  - consistency
* is controlled by the composition and temperature of the magma
  - in the system by blending surfactants
  - dispositions
  - highly temperature dependent, and has common units of centipoise
  - how hard it is for the fluid to move or flow
* is internal friction
  - resistance to flow of a liquid
* is measured in terms of flow with water as the base standard
  - with various types of viscometers and rheometers
  - on the x-axis and increases to the right
  - reduced by water and a lower silica content
* is the ability of a substance to resist flow
  - degree to which a fluid resists flow under an applied force
* is the degree to which fluid resists flow of an applied force
  - resists under an applied force
  - level of thickness or thinness on a liquid
  - lubricating capability of a lubricant
* is the measure of a liquid's resistance to flow
  - how thick an oil is
  - resistance of a fluid to flow
  - the resistance to flow of a material when exposed to a shear stress
* is the most important physical property of a lubricant
  - single property of lube oil
  - oil's ability to flow at a given temperature
  - physical property of any fluid to resist flow when pressure is applied
  - property of fluid to resist flow
  - ratio of shear stress to the rate of shear strain
* is the resistance of a liquid to flow
  - to motion
  - therefore, deformation is directly related to viscosity
* lies behind the skin friction component of drag.
* macroscopic transport property of a fluid.
* makes a real difference in fluid performance.
* means resistance to pouring.
* measure of a fluid's resistance to flow
  - thickness or resistance to move
  - fluids resistance to relative motion within the fluid
  - lubricant's resistance to flow
* measure of an oil's flow characteristics, or thickness, at a certain temperature
* measure of how fluid a magma is
  - resistive a fluid is to flow
  - resistance to local change
* measure of the ease with which molecules move past one another
  - flow characteristics of a liquid
  - friction, or resistance to flow, in a fluid
  - oil's thickness
* measurement of resistance to flow or how thick or thin an oil is.
* molecular property of fluid.
* occurs on a cellular level.
* offers the ability to change the Blend Mode of a layer.
* physical property of a liquid that describes how well it flows
  - liquids that descibes how they flow
* refers to an oil's resistance to flow.
* refers to the body or flowability of an oil
  - compound's resistance to flow
  - rate of resistance to flow
  - thickness of the oil
* remains constant at all temperatures.
* result of the internal friction of the material's molecules.
* tells how well a material clings to itself.
* varies with temperature and composition of liquid.
* very important subject in both chemistry and chemical engineering.
+ Friction: Force
  * Internal friction in a fluid is called viscosity. Viscosity is how hard it is for the fluid to move or flow.
