Question

Average velocity for mass balance in flow down vertical plate. For a layer of liquid flowing in a
laminar flowing in laminar flow in the z direction down a vertical plate or surface, the velocity profile
is in image

Where δ is the thickness of the layer, x is the distance from the free surface of the liquid towards the
plate and Vz is the velocity at a distance x from the free surface
a) What is the maximum velocity Vz,max?
b) Derive the expression for the average velocity Vz,ave, and also relative it to Vz,max.
