Question
Water has to be supplied to a town with one lakh
population at the rate of 150 litre/capita/day from a river
2000 m away. The difference in elevation between the
lowest water level in the sump and reservoir is 40 m. If
the demand has to be supplied in 8 hrs, determine the
size of the main and the brake horse power of the pumps
required. Assume maximum demand as 1.5 times the
average demand. Assume f= 0.03, velocity in the pipe =
2.4 m/s and efficiency of pump =80%
