Water is pumped from a lake to reservoir using a pump which exerts 25 kW of useful mechanical power to the water. If the flow rate of the water is measured to be 0.035 m³/s and the free surface of the reservoir is 60 m higher than the surface of the lake, determine the irreversible head loss of the system and the lost mechanical power during this process. Draw your schematic/ free-body diagram.
