A single acting reciprocating compressor runs at 420rev/min and takes in air at 1 bar and at 20°C and compresses it in 3 stages to 60 bar, which returns the air to 20°C. The free air delivery is available from the data table. Each stage has one piston with a stroke of 100mm. Calculate the following:
ideal pressure between each stage;
ideal indicated power at each stage;
heat rejected fro each cylinder;
heat rejected from each intercooler;
isothermal efficiency;
swept volume at each stage;
bore of each cylinder.
Ignore leakage and clearance volume. compression is 1.3
