How to measure kinematic viscosity

WebKinematic viscosity of petroleum products testerScopeStandard: ASTM D445This instrument is used to measure the kinematic viscosity of liquid petroleum produc... WebKinematic Viscosity Converter. Kinematic viscosity is defined as the ratio of absolute or dynamic viscosity to density. Kinematic viscosity can be obtained by dividing the absolute viscosity of a fluid with its mass density. In the SI the unit is m²/s. However, the commonly used measure is the stokes (or stoke) where 1 St = 10⁻⁴ m²/s.

WebKinematic Viscosity Definition: The absolute viscosity of a fluid divided by the density of the fluid. Also known as the coefficient of kinematic viscosity. Measured in stokes (St) or centistokes (cSt). One centistoke = 0.01 stokes. The metric unit is square metres per second (m2/s). A common WebIn fluids, kinematic viscosity is the ratio of dynamic viscosity to density. Mathematically given by-. ν = η ρ. Where, ν is the kinematic viscosity. η is the dynamic viscosity / absolute viscosity. ρ is the density. Refer to the table given below for definitions, units, and symbols for the above parameter.
