A water pump is attached to an electric motor. The inlet and outlet diameters of the pump are the same. The volume flow rate of water through the pump is 0.1 m^3/s. Assume that the effiiciency of the pump is 80% while the efficiency of electric motor is 90&.

1. What is the energy balance equation for the compbined pump motor system?

2. What is the relationship (equation) between the input power of the electric motor and the pressure rise of the water?

3. If the electric power into the system is 30kW what is the total rate of energy lost?
