A 3-stroke cycle is executed in a closed system with 1 kg of air, and it consists of the following three processes: (a) Isentropic compression from 100 kPa, 300 K to 800 kPa. (b) p=constant heat addition in amount of 2000 kJ. (c) p=cV heat rejection to initial state.
(i) Calculate the maximum temperature and efficiency.
(ii) Show the cycle on T-s and p-v diagrams. Assume cold air standard. What-if-scenario: How would the conclusion change if (b) constant pressure heat addition amounted to 1000 kJ?
