Air compressor theoretical issues

by Carmel
(USA)

A two cylinder reciprocating air compressor, each cylinder having a maximum volume of 600cc (cubic centimetres), operates at a speed of 1500RPM, increasing the pressure of atmospheric air from 100kPa to 600kPa. Air temperature at the start of compression is 298k, a thermometer on the compressor outlet reads 453k, and a flow meter measures an air intake rate of 1.35 m3/minute.
(a)What is the index of compression?
(b)Determine the cylinder volume at which the inlet valve opens, and assuming that the index of expansion is the same as the index of compression, determine the clearance volume.
(c)Calculate the volumetric efficiency of the compressor, and its limiting pressure (ie the
outlet pressure at which volumetric efficiency reaches zero).
(d) Calculate the power input to the compressor.

Huh?? Hey Carmel. Nice to hear from you. You need an engineer's help, not a shop floor guy like me.

Good luck.
