Transcribed Image Text:A pump draws water through a 300-mm diameter cast iron pipe, 15m long from a reservoir
in which the water surface is 4.5 m higher than the pump and discharges through a 250-
mm diameter cast iron, 75 m long, to an elevated tank in which the water surface is 60 m
higher than the pump. Q = 0.25 m³/s. Considering f= 0.02 and the coefficients for minor
head losses (k entrance = 0.5, k hend = 0.35, and K exit 0.5), compute the power of the pump.
