2.18 The velocity distribution for laminar flow between parallel plates is given by

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 10 m s and h=0 1 mm. Calculate the shear stress on the upper plate and give its direction. Sketch the variation of shear stress across the channel.
