An air standard 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, 27oC to 700 kPa,
(2) p = constant during heat addition to initial specific volume, (3) v = constant 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.
