Question

A single reciprocating compressor takes 1m³ of air per minute and 1.013 bar and 15 degree Celsius and delivers at 7 bar. Assuming Adiabatic law(n=1.35) and no clearance.

Calculate:

  • Mass flow rate
  • Delivery temperature
  • Indicated power

This same compressor is now driven at 300 rpm, has a stroke bore ratio of (1.5:1), it has a mechanical efficiency for the compressor of 85% and motor transmission efficiency of 90%.

Calculate:

  • Volume per cycle
  • Cylinder bore diameter
  • Power to the compressor
  • Motor power needed
  • The isothermal power
  • The isothermal efficiency
