Water from a nearby lake is to be used for a fountain and a water tank. The figure below shows the elevations and pipe connections. It is desired that the jet water of the fountain reaches a height of at least 2.5 m from the nozzle outlet. As for the tank, it is elevated in order for it to distribute water using gravity. The specifications of nozzle, suction and discharge pipes are given in the table below. Assuming negligible minor head losses, what is the minimum power input to the pump in kW? Take pump efficiency to be 88% and motor efficiency, 95%. Water from the fountain is returned to the lake through a drainage (not shown in the figure). round off the answer to 4 decimal places
