9-16 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. | |
