Air compressor is a single acting two cylinder unit which takes in an air volume of 0.2 m3/s. The initial absolute pressure is .1 MPa. The final pressure is .7 MPa. Consider intermediate compression to be ideal and perfect intercooling. The compressor runs at 600 RPM. The index of compression is 1.25.
(a) Find the intermediate pressure
(b) The total volume of the cylinders
(c) Work done per cycle.
