Liquids - Kinematic Viscosities

Sponsored Links

Viscosity is resistance to shear or flow in a fluid - and a measure of the adhesive/cohesive or frictional property. Viscosity arising due to internal molecular friction produces the frictional drag effect.

There are two related measures of fluid viscosity - known as dynamic (or absolute) and kinematic viscosity.

Kinematic viscosities of some common liquids:
