Question

The velocity distribution for laminar flow between parallel plates

Answer 1

given by

u/umax = 1- (2y/h)^2

where h is the distance separating the plates and the origin is placed midway between the plates. Consider a flow of water at 15 C, with umax = 0.30m / sec and h = 0.50mm. Calculate the shear stress on the upper plate and give its direction.
