Answer to Question #150497 in Thermal Power Engineering for Ferdinand

Question

A fluid at 5.15 bar is expanded reversibly according to a law PV = constant to a pressure of 2.15 bar until it has a specific volume of 0.22 m3/kg. It is then cooled reversibly at a constant pressure, then is cooled at constant volume until the pressure is 0.82 bar; and is then allowed to compress reversibly according to a law PVn = constant back to the initial conditions. The work done in the constant pressure is 0.625 kJ, and the mass of fluid present is 0.32 kg. Calculate the value of n in the fourth process, the net work of the cycle and sketch the cycle on a P-V diagram
