Question

An air-standard cycle is executed within a closed piston–cylinder system, and it consists of the following three processes:

1–2 V = Constant heat addition from 100 kPa and 32°C to 850 kPa

2–3 Isothermal expansion until V3 = 8.5V2

3–1 P = Constant heat rejection to the initial state Assume air has constant properties with cv = 0.718 kJ/kg·K, cp = 1.005 kJ/kg·K, R = 0.287 kJ/kg·K, and k = 1.4.

Determine the cycle thermal efficiency.
