C)the work done per kgm for each process, and D) the cycle thermal efficiency
A single-acting compressor completes one compression cycle with one revolution of the crank. And for a double-acting compressor completes two compression cycles with one revolution of the crank. 0.013 m³ S Gas is compressed in a reciprocating compressor from 1 bar to 6 bar. The free air delivery is The clearance ratio is 0.05. The expansion process of the cycle follows the law of pv12 = C. The crank speed is 360 rev/min.
