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 sucLon pipe is 350mm in diameter 
and 12m in length and the delivery pipe is 550mm in diameter and 40m in length. Calculate:
(a) 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) 
(b) the energy to be supplied by the pump per unit mass of water transferred 
(c) The input power required by the pump, which is 60 % efficient
