Calculate the exergy destruction for each process of Stirling cycle of Prob. 9-74, in kJ/kg.
Prob. 9-74:
An air-standard Stirling cycle operates with a maximum pressure of 3600 kPa and a minimum pressure of 50 kPa. The maximum volume is 12 times the minimum volume, and the low-temperature reservoir is at 20°C. Allowing a 5°C temperature difference between the external reservoirs and the air when appropriate, calculate the specific heat added to the cycle and its net specific work.
