Consider a Carnot cycle executed in a closed system with 0.5 kg of air. The temperature limits are 50oC and 750oC, and the pressure limits are 15 kPa and 1700 kPa. Heat addition takes place from a reservoir at 775oC and heat rejection takes place to the atmosphere at 100 kPa, 25oC.
(a) What is the energetic efficiency of the Carnot engine?
(b) Perform a complete energy inventory and draw an energy flow diagram for the cycle on unit mass basis (kJ/kg). Use the PG model for air
