A pump draws water from a 20 cm diam suction pipe and discharges through a 15 cm diam pipe in which the velocity is 3.60 m/s. The pressure is – 34. 465 kPa at A in the suction pipe. The 15 cm diam pipe discharges horizontally into air at C inclined at 45 degrees. Find the maximum height and range that the water can reach if B is 1.8 m. above A and 20 hp is delivered to the pump? Assume that the pump operates at 80 % efficiency and that the frictional loss in the pipe between A and C is 3 m.
