Question

Answer the followwing problem:

  1. Determine the number of stages needed for a centrifugal pump if it is used to deliver 600gal/min of water and pump power of 15Hp. Each impeller develops head of 38ft.
  2. Calculate the compressor work in kJ required to compress 1 kg of an ideal gas from an initial volume and pressure of 0.65m3 and 101.3kpa to a final pressure of 517kpa & volume of 0.1943m3.
    ANS. 133.549
  3. An air compressor takes air at 97kpa at the rate of 0.4m3/s and discharges to 650kpa. If power input to the compressor is 110kw, determine the heat loss(kw) in the compressor.
    ANS. 11.948
