Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Unit of kinematic viscosity is defined as
A
Dynes/sec/cm
B
poise
C
Dynes/cm
D
Stoke
Explanation: 

Detailed explanation-1: -The kinematic viscosity [m2/s] is the ratio between the dynamic viscosity [Pa. s = 1 kg/m·s] and the density of a fluid [kg/m3]. The SI unit of the kinematic viscosity is m2/s. Other units are: 1 St (Stoke) = 1 cm2/s = 10−4 m2/s.

Detailed explanation-2: -The stoke (British “stokes”), a unit of kinematic viscosity in the centimetre-gram-second system, was named after him in 1928.
