A fluid is heated reversibly at a constant pressure of 1.05 bar until it has a specific volume of 0.1 m³/kg. It is then
compressed reversibly according to a law pv = constant to a pressure of 4.2 bar, then allowed to expand reversibly
according to a law pv 17 = 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.
