Estimate the shaft power (in Horsepower) requirement to pump 247,063 L/hr of water available at 25oC and atmospheric pressure from a storage tank. The rated differential head requirement is 31 m.
Assume the efficiency of the pump to be 65%.
At 25oC, the density of the water = 0.994 g/cm3
Gravitation force = 9.8 m/s2
