A pump is to deliver water at a rate of 1.4 m³/s from a sump to reservoir which is 10 km away through a steel pipe 1200 mm in diameter for a length of 5 km and the remaining through a PSC pipe of diameter 1000 mm. The elevation difference between the full tank level of the delivery reservoir and the low water level of the sump is 50 m. What is the Break Horse Power (in kW) requirement of the motor? Assume the pump house loss of 3.75 m and minor losses to be 10% of the friction losses. Use Darcy-Weisbach friction factor (f) of 0.018 for steel pipe and 0.02 for PSC nine with a nump efficiency of 80%
