Question

A pump is required to transfer water at the rate of 350 kg/s from an open sump to an open storage tank located  30m above the pump.  The suction pipe is 350mm in diameter and 12m in length, and the delivery pipe is 550mm in diameter and 40m in length. The friction factor of the pipe system is f=0.005. 

Q1. Calculate the maximum height at which the pump may be placed above the sump, so that pressure at the inlet is not less than -80 kPa (gauge) (m)

Q2. Calculate  the energy to be supplied by the pump per unit mass of water transferred (J/Kg)

Q3. Calculate the input power required by the pump, which is 60 % efficient (kW)
