A heat engine working according to Carnot cycle with 1 mole of air as a working fluid. The gas expands isothermally from 200 ° C, 500 Pa, 7.865 m to 393.25 Pa, 10 m ?. Then it expands adiabatically to 222.915 Pa and 15 m³. After that it compresses isothermally to a particular values of pressure and volume. And finally it returns to its initial state adiabatically. Take Cp / Cy for air as 1.4, calculate the heat absorbed, heat rejected, net work done and the engine efficiency.
