Question

Coefficient of viscosity density dimensional formula

Answer 1

Answer:

Coefficient of viscosity is defined as tangential force required to maintain a unit velocity gradient between two parallel layers of liquid of unit area. Mathematically, Coefficient of viscosity (η)= Fr/Av ——- F= tangential Force, Area, r= distance between the layers, v= velocity

Explanation:

Enter your search terms: 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.
