Q1:

In C.G.S. system the units of kinematic viscosity, is

A stoke

B poise

C Newton

D none of these.

ANS:A - stoke

In the CGS (Centimeter-Gram-Second) system, the unit of kinematic viscosity is the stokes (symbol: St). The stokes (St) is defined as cm2/scm2/s in the CGS system. It is named after the British scientist George Gabriel Stokes, who made significant contributions to fluid dynamics. Therefore, the correct unit of kinematic viscosity in the CGS system is the stoke (St)
