A pump draws water from a tank through a 20 cm diameter suction pipe and discharges it through a 15 cm pipe in which the velocity is 4.0 m/s. The 15 cm pipe discharges horizontally into air. To what height above the surface of the tank can the water be pumped if 33kW are delivered to the pump? Assume that the pump operates at 70% efficiency and that the head loss in the discharge pipe is equivalent to 2v2/2g.
