9 Water is pumped from a lake to a storage tank 18 m above at a rate of 70 L/s while consuming 20.4 kW of electric power. The top of the tank is open to the atmosphere. Disregarding any frictional losses in the pipes and any changes in kinetic energy, determine the overall efficiency of the pump-motor unit. Draw the schematic diagram and show your detailed solution. Answer in percentage. 18 m Pump Storage
