Water is pumped from a lake to a storage tank 15 m above at a rate of 70 L/s while consuming 15.4 kW of electric power. Disregarding any frictional losses in the pipes and any changes in kinetic energy, determine (a) the overall efficiency of the pump–motor unit and (b) the pressure difference between the inlet and the exit of the pump.

Water is pumped from a lake to a storage tank 15 m
above at a rate of 70 L/s while consuming 15.4 kW of electric
power. Disregarding any frictional losses in the pipes and
any changes in kinetic energy, determine (a) the overall efficiency
of the pump–motor unit and (b) the pressure difference
between the inlet and the exit of the pump.
