A Carnot cycle uses air as a working fluid. The temperatures of the high-and low-temperature reservoirs are 300 and 0°C. The pressures of the air at the beginning and the end of the meat-addition process are 800 and 100 Kra, respectively.

Draw both the 7-s and P-v diagrams for the cycle. Determine the following:

1. The thermal efficiency of the cycle
2. The amount of heat absorbed from the high-temperature reservoir per unit mass of working fluid
3. The amount of heat rejected to the low-temperature reservoir per unit mass of working fluid
4. The network provided by the cycle per unit mass of working fluid
5. The irreversibility of the cycle.
