Fluid viscosity is generally measured in two different terms Dynamic Viscosity () and Kinematic Viscosity ( v). Dynamic Viscosity is also called as Absolute Viscosity and it is related to Kinematic Viscosity.
Mathematically,
Kinematic Viscosity, v = /
It means that Kinematic Viscosity is the ratio of Dynamic Viscosity of one substance to the density of the same substance.
Unit:
S.I. unit of Kinematic Viscosity is m2/s
Sometimes it is also written in form of Stokes (St)
1 Stoke = 10-4m2/s
= 1 cm2/s
In centiStokecSt),
1 cSt = 10-6m2/s (1 Stoke = 100 cSt)
