An electric motor converts electricity to rotating shaft work with an efficiency of 42%. The rotating shaft turns the impeller in the pump which, in turn, increases the pressure of the water by 300kPa. If the motor is consuming 3.8 kW of electricity, and water flow through the pump is 4.18 Liter/sec, what is the mechanical efficiency with which the pump converts the rotation of the impeller into water pressure?
