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. To what height h above B can the water be raised 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.

3. 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. To what height h above B can the water be raised 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. Given: Suction pipe Discharge pipe 1.80 m pump Datum line DA = 20 cm = 0.20 m De = Dc = 15 cm 0.15 m PA=- 34.465 KPa (suction pressure) Ve = Vc = 3.6 m/s Pc 0 (atmospheric pressure) BHP = 20 hp Pump efficiency = 80% HLA-C) = 3 m Required:
