1. A fluid undergoes the following processes: a. Heated reversibly at a constant pressure of 1.05 bar until it has a specific volume of 0.1 m3/kg. b. It is then compressed reversible according to the law pv = constant to a pressure of 4.2 bar. c. It is then allowed to expand reversibly according to the law pyl.3 = constant. d. Finally, it is heated at constant volume back to initial conditions. The work done in the constant pressure process is 515 Nm and the mass of fluid present is 0.2 kg. Calculate the net work done on or by the fluid in the cycle and sketch the cycle on a p-v diagram.
