When water is pumped into a water tank 20 m above a lake with a flow rate of 70 l/s, 20.4kW of electrical power is consumed. Determine the efficiency of the pump-motor group by ignoring the friction losses in the pipes and the change in kinetic energy. Calculate the efficiency of the pump-motor group.
