Problem 4 Consider a gas power cycle executed in a closed system with 0.08 kg of gas. The gas is initially at 120 kPa, 2°C. First,910 kJ/kg of heat is added under constant volume. Then, more heat is added under constant pressure such that the gas reaches 1387°C. Then, the gas is expanded isentropically to 120 kPa. Finally, heat is rejected from the system under constant pressure such that it returns the gas to its initial state. Assuming air-standard cycle...
