Air is heated reversibly at a constant pressure of 0.5 bar until a volume of 0.5 m^3. It is then compressed adiabatically to a pressure of 3 bar, then allowed to expand isothermally and is finally heated at constant volume back to the initial conditions. The work done in the constant pressure process is 10 kJ and the mass of air is 0.4 kg. Calculate the net work of the cycle and sketch the cycle on a p - v diagram.
