Question

State stroke’s law and write its application.​

Answer 1

Answer:

Stokes law is the basis of the falling-sphere viscometer, in which the fluid is stationary in a vertical glass tube. ... Knowing the terminal velocity, the size and density of the sphere, and the density of the liquid, Stokes' law can be used to calculate the viscosity of the fluid.

Answer 2

Answer:

According to Stokes law, if a spherical body falls into a viscous liquid then the force acting at the interface is proportional to – Radius of the spherical body, velocity of the sphere, and viscosity of this given fluid.
