A centrifugal pump delivers water at the rate of 0.22 m³/s from a reservoir at ground level to another reservoir at a height H, through a vertical pipe of 0.2 m diameter. Both the reservoirs are open to atmosphere. The power input to the pump is 90 kW and it operates with an efficiency of 75%. Data: Fanning friction factor for pipe flow is f = 0.004. Neglect other head losses. Take gravitational acceleration, g = 9.8 m/s² and density of water is 1000 kg/m³. The height H, in meters, to which the water can be delivered (up to one decimal place) is _______.
Correct : 26.0
