kinematic viscosity

[¦kin·ə¦mad·ik vi′skäs·əd·ē]
(fluid mechanics)
The absolute viscosity of a fluid divided by its density. Also known as coefficient of kinematic viscosity.

Kinematic Viscosity


(also kinematic modulus of viscosity), the ratio of the conventional modulus of viscosity η (also called the dynamic coefficient) to the density of the substance ρ; it is designated by ν. In the International System of Units the unit of kinematic viscosity is m2/sec. A fractional unit of kinematic viscosity, cm2/sec, is called the stokes: 1 m2/sec = 104 stokes.
