6. A pump is delivering water from the surface of a lake to a tank 20m above at a rate of 70L/s while the pump label suggests it consumes 18kW of electric power. If all the loses and any changes of kinetic energy are negligible, a. What is the pump efficiency? b. What is the pressure rise of water in the pump?
