A cycle composed of three processes: poly tropic compression (n=1.5) from 137 kPa and 38 degrees C to state 2, constant pressure from state 2 to state 3 and constant volume from state 3 to state 1. The heat rejected is 1560kj/kg and the substance is air. Determine:

1. The pressures, the temperatures, and specific volumes around the cycle

2. The heat added

3. The work for each process and the net work.
