A pump draws water through a 150 mm diameter pipe from a reservoir whose surface level is at datum level and discharges it through a 100 mm diameter pipe to another reservoir whose surface level is 72 m above datum level. The pump is situated 6 m below datum.The loss of head in the 150 mm suction pipe is three times the velocity head in the 150 mm pipe and the loss of head in the 100 mm delivery pipe is 20 times the velocity head in the 100 mm pipe. Calculate the power output of the pump and the pressure heads at the inlet and outlet of the pump when discharge is
a)0.91 m3/min
B)2.73 m3/min
