2. A tank containing water to a depth of 2.5m is accelerated upward at 3.6m/s2. Calculate the pressure on the bottom of the tank. (20％).

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
