Grease kinematic viscosity
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. Water at 20 ... WebViscosity. A measure of a fluid’s resistance to flow. For lubricants, a proper viscosity must guarantee an adequate separation between surfaces without causing too much friction. …
