Calculate the kw input to the pump

Reference no: EM13254943

Water is drawn from a reservoir through a vertical 300-mm diameter pipe by a pump which discharges it into a horizontal 150-mm diameter pipe. The inlet pressure gage reads a gage pressure of -20kPa, while the discharge pressure gage shows an absolute pressure of 150kPa for a discharge rate of 0.05 m^3/s. Calculate the kW input to the pump:

A) For efficiency: 100%

B) For efficiency: 80%
