A 150 kW water pump is expected to generate a head of 105m across the pump when running at best efficiency point, BEP, at a speed of 2500 rpm. If the efficiency of the pump is 77%, determine the specific speed and suggest the type of the pump best suited to this duty.
Assumptions: Take g = 9.81 m/s2 and the density and kinematic energy of water as 1000 kg/m3 and 1 × 10-6 m2/s
The question belongs to Chemistry and it discusses about calculating the speed of a water pump and suggest the type of pump best suited.
