The pump shown draws water (20°C) through a 20 cm suction pipe and discharges it through a 11 cm pipe in which the velocity is 3 m/s. The 10 cm pipe discharges horizontally into air at point C. To what height h above the water surface at A can the water be raised if 28 kW is delivered to the pump? Assume that the pump operates at 60% efficiency and that the head loss in the pipe between A and C is equal to 2 V²C /2g. Assume α = 1.0 throughout.
