WebAug 11, 2024 · The kinematic viscosity of a fluid is the ratio of the viscosity of the fluid to the fluid's density. Mathematically, it is expressed as: where ν is the kinematic … WebKinematic 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. Its symbol is St. In engineering, centistokes (cSt) are usually used. 1 St = 100 cSt or 1 cSt = 10⁻⁶ m²/s.

What is a Kinematic Viscosity? - Definition from …
WebThe absolute or dynamic viscosity is equal to the kinematic viscosity, multiplied by the density of the fluid. It is usually expressed in centipoise (cP) (1 cP = 0.001 Pa.s). Viscosity index (VI) The viscosity of lubricating oil changes with temperature and the rate of change depends on the composition of the oil. 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) … WebThe Reynolds number for a pipe or duct expressed in Imperial units. Re = 7745.8 u dh / ν (2a) where. Re = Reynolds Number (non dimensional) u = velocity (ft/s) dh = hydraulic diameter (in) ν = kinematic viscosity (cSt) (1 cSt = 10-6 m2/s ) The Reynolds Number can be used to determine if flow is laminar, transient or turbulent. The flow is. gravity method
