A 3-stroke cycle is executed in a closed system with 1 kg of air, and it consists of the following three processes: (1) Isentropic compression from 100 kPa, 300 K to 800 kPa, (2) p = constant during heat addition in amount of 2000 kJ, (3) p = cv during heat rejection to initial state. Calculate
(a) The maximum temperature and
(b) Efficiency. Show the cycle on T-s and p-v diagrams. Use the PG model for air.
