The velocity distribution for laminar flow between parallel plates is given by (see picture) h is distance separating the plates. Origin is placed midway between them. A flow of water is at 15 C with umax = 0.10 m/s amd h = 0.1mm. Calculate the shear stress on the upper plate and give its direction. Sketch the variation of shear stress across the channel
