Solve the below problem:
Q: An air-standard cycle with variable specific heats is executed in a closed system with 0.003 kg of air, and it consists of the following three processes:
1-2 Isentropic compression from 100 kPa and 27°C to 700 kPa
2-3 P = constant heat addition to initial specific volume
3-1 v = constant heat rejection to initial state
(a) Show the cycle on P-v and T-s diagrams.
(b) Calculate the maximum temperature in the cycle.
(c) Determine the thermal efficiency.
