Q2 A vertical jet of water of diameter 20 mm and with velocity 20 m/s strikes a curved cup as shown in Figure 2 below. Determine the force on the cup if Figure 2 Vertical Curved Cup a) frictional losses are neglected (5 marks) b) friction causes a reduction in velocity of 5% of the water leaving the cup (5 marks) c) the angle of water leaving the cup is 10° and frictional losses are neglected (5 marks) d) the angle of water leaving the cup is 30° and friction causes a reduction in velocity of 15 % of the water leaving the cup (5 marks)
