Question: An air-standard cycle is executed in a closed system and is composed of the following four processes: 1-2 Isentropic compression from 100 kPa and 27C

An air-standard cycle is executed in a closed system and is composed of the following four processes:
1-2 Isentropic compression from 100 kPa and 27°C to 1 MPa
2-3 P = constant heat addition in amount of 2800 kJ/kg
3-4 v = constant heat rejection to 100 kPa
4-1 P = 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.
Assume constant specific heats at room temperature.
