Let us consider a standard air cycle with variable specific heats, where 0.003 kg of air is added as the working fluid. The complete cycle is composed of: 1-2 Addition of heat at v=cte of 95 kPa and 17°C up to 380 kPa. 2-3 Isentropic expansion up to 95 kPa. 3-1 Heat rejection at P=cte up to the initial state. Determine the net work done by the cycle and the thermal efficiency.
