Question #142984

In a stream of glycerine in motion, at a certain point the velocity gradient is 0.25 metre per sec per metre . The mass density of fluid is 1268.4 kg per cubic metre and kinematic viscosity is 6.30 x 10^-4 square metre per second. Calculate the shear stress at the point.

Expert's answer

By the Newton's Law of Viscosity

Kinematic viscosity is defined as the ratio between the dynamic viscosity and and density of fluid.

Substitute

Given

The shear stress at the point is
