(2)运动粘度:在温度t℃时,运动粘度用符号γ表示,在国际单位制中,运动粘度单位为斯,即每秒平方米(m2/s),实际测定中常用厘斯,(cst)表示厘斯的单位为每秒平方毫米(即 1cst=1mm2/s)。运动粘度广泛用于测定喷气燃料油、柴油、润滑油等液体石油产品深色石油产品、使用后的润滑油、原油等的粘度,运动粘度的测定采用逆...

usually expressed as centiPoise,cP. This unit is named in honor of Jean Léonard Marie Poiseuille (seeFigure 1). CentiPoise is commonly used to express dynamic viscosity because water at 20°C has a viscosity of 1.002.
Water has a viscosity of 1.0 cP (dynamic viscosity) or 1.0 cSt (kinematic viscosity) at 60°F. In comparison, Alaskan North Slope (ANS) crude oil has a viscosity of 200 SSU (43.33 cSt) at 60°F. Values of viscosity in SSU and SSF may be converted to their equivalent kinematic viscosi...
This property is called absolute viscosity (also known as dynamic viscosity) and is measured in centipoises (cP). The other consideration is how the fluid behaves only under the force of gravity. This is called centistokes, which we have already noted. The two are related through the ...
cSt x specific gravity = cP AND cP ÷ specific gravity = cSt Let’s look at a few of the most common examples of each type of viscometer. Kinematic Viscometers VISCOSITY CUPS –A specific measured volume cup with a small orifice at the bottom. Viscosity cups work on the same pour test...

Centipoise (cP) is commonly used to describe dynamic viscosity because water at a temperature of 20°C has a viscosity of 1.002 Centipoise. This value must be converted back to 1.002 x 10^-3 Pa•s for use in calculations. Kinematic Viscosity ...
