Flow is said to be steady if

in laminar flow

At large flow velocities the flow of a fluid becomes

If a ball is spinning in an airflow it develops pressure difference between the lower and upper faces due differences in the

The lift on an aircraft wing arises because of

The coefficient of viscosity for a fluid is defined as the ratio of

According to Stokes’ law if η is the coefficient of viscosity, 'R' the radius of the sphere and it is moving with a velocity v the viscous drag force F is given by
