The velocity distribution for laminar flow between parallel plates is given by \frac{u}{u_{\max }}=1-\left(\frac{2 y}{h}\right)^{2} where h is the distance separating the plates and the origin is placed midway between

the plates. Consider flow of water at 15 C with maximum speed of 0.05 m/sec and h = 5 mm. Calculate the force on a 0.3 m2 section of the lower plate and give its direction.
