A fluid is heated reversibly at a constant pressure of 1.05 bar until it has a specific volume of 0.1 m'/kg. It is then compressed reversibly according to a law pu constant to a pressure of 4.2 bar, then allowed to expand reversibly according to a law - constant, and is finally heated at constant volume back to the initial conditions. The work done in the constant pressure process is -515 N m, and the mass of fluid present is 0.2 kg. Calculate the net work of the cycle and sketch the cycle on a p- diagram.

Question
A fluid is heated reversibly at a constant pressure of 1.05 bar until it has a specific volume of 0.1 m'/kg. It is then compressed reversibly according to a law pu = constant to a pressure of 4.2 bar, then allowed to expand reversibly according to a law pel.- constant, and is finally heated at constant volume back to the initial conditions. The work done in the constant pressure process is -515 N m, and the mass of fluid present is 0.2 kg. Calculate the net work of the cycle and sketch the cycle on a p-v diagram.
