An air-standard cycle with variable specific heats is executed in a closed system with 0.0045 kg of air and consists of the following three processes: 1–2 v = Constant heat addition from 95 kPa and 17°C to 380 kPa 2–3 Isentropic expansion to 95 kPa 3–1 P = Constant heat rejection to initial state Use data from tables. Calculate the thermal efficiency % ? Hint : The answer should be a percenta
