Question

what is coefficient of viscosity​

Answer 1

The ratio of the shearing stress to the velocity gradient is a measure of the viscosity of the fluid and is called the coefficient of viscosity η, or η= Fx / Av. The cgs unit for measuring the coefficient of viscosity is the poise.

Answer 2

Explanation:

an applied force, measured by the tangential friction force per unit area divided by the velocity gradient under conditions of streamline flow.is called coefficient of viscosity

η, or η= Fx / Av.
