Water at 20 Degree C is pumped at a constant rate of 9m^3/h from a large resevoir resting on the floor to the open top of a anexperimental absorption tower. The point of dicharge is 5 m abovethe floor, and friction losses in the 50 mm pipe from the resevoirto the tower amount to 2.5 J/kg. At what height in the resevoirmust the water level be kept if the pump can deliver only 0.1kW?
