1. A layer of water flows down an inclined fixed surface with the velocity profile shown in Fig. 1. Determine the magnitude of shearing stress that water exerts on the fixed surface forU = 4 m/s and h= 0.3m. (20％). Fig. 1

3. Assuming ideal flow in a horizontal plane, calculate the magnitude and direction of the resultant force on the stationary blade in Fig. 2, knowing that Vj=12m/s and Dj=150mm. Note that the jet is divided by the splitter so that one-third of the water is diverted toward A. (20％). Fig. 2
