The viscosity of a substance will change with both temperature and pressure. For liquids the changes induced by a change in temperature are usually more readily observed than the changes from pressure because liquids are only slightly compressible with pressure. In gasses, the changes in viscosity with pressure are much more easily demonstrated because gases are, almost by definition, quite compressible so that the density can be easily changed by either changes in pressure or changes in temperature.

What is the difference between a compressible fluid and an incompressible fluid?
The density of a compressible fluid changes with pressure, while the density of an incompressible fluid is not affected by pressure (assuming isothermal conditions).
How you can control the viscosity of HTPB during production?
keep temperature in control
What is a boiler reheater?
In a reheat turbine the stean first enters high speed turbine so its temp and pressure reduces before entering low speed turbine so a reheater is used to reheat the cooled steam
What is the zero shear viscosity?
The zero shear viscosity is the value of the apparent viscosity (quotient between shear stress and shear rate) of a liquid in the limit of zero shear rate (i.e., when the fluid it is at rest). Therefore it is not the result of a direct measure but a calculus or interpolation from experimental results at the lower shear rates values. The most important thing is its physical meaning. It represents the ability of the material to avoid sedimentation when storage. A high zero shear viscosity is interpreted as a the material will show homogeneous during long storage.
Can you change a central unit from freon 22 to 134a?
the straight easy answer is no. Although,I guess id one really wanted to,you could change the compressor oil,Expansion valve,& basically re-engineer the system you could. But as far as removing the R-22,& recharcing with R134A,definately no.the temperature to pressure relationship is way different in the 2 refrigerants(with 134A running at a lower temp & pressure vs. r-22)
Does water viscosity changes with pressure?
yes
What is the freon pressure for an air conditioner?
It changes based on vehicle, outside temp, and desired inside temp. Pressuse depends on ambient temperature, the higher the temp, the greater the pressure
What turns from a liquid to gas?
Variation of pressure and temperature..that changes. Gas into liquid..temp should be decreased likewise pressure..
What is the viscosity of milk at room temp?
roughly three centepoise
What is the effect of pressure on viscosity?
As temperature increases viscosity decreases.
Conditons in which color and viscosity of saliva changes?
causes are change the color and viscosity saliva
How does heating a liquid affect the viscosity and why?
it affects the viscosity because the liquid changes the shape and turns it to a gas and the viscosity by change the form
Why would your oil pressure drop at running temp on your Dodge Magnum rt?
This is normal as when the engine warms the viscosity of oil lessens, thus also reducing the oil pressure. On a cold start the oil pressure is on the high side, say reads at 75 at idle, then at operating temperature it can just read between 25 to 50 at idle speed, depending on which viscosity rating of the oil you use.
How the coefficient of viscosity of a liquid changes with temperature?
The coefficient of viscosity of liquids decreases with an increases in temperature.
Viscosity breaksdown occurs when?
The oil reaches a temp too high to maintain viscosity capabilities. Usually higher than the operating temperature of a vehcile.
What is the viscosity of the blood?
The viscosity of blood (cells + plasma) at 36.6 degrees Celsius (normal body temp) is 0.0027 [N-s/m^2].
What are factors that affect viscosity and flow?
Pressure and temperature are the two factors that affect flow and viscosity. Viscosity refers to the resistance of a liquid to the shear forces.
