Question

I kg of a fluid expands reversibly according to a linear law from 4.2 bar to 1.4 bar; the initia] and final volumes are 0.004 m) and 0.02 m). The fluid is then cooled reversibly at constant pressure, and finally compressed reversibly according to a law po = constant back to the initial conditions of 4.2 bar and 0.004 m '. Calculate the work done in each process and the net work of the cycle. Sketch the cycle on a. p-v diagram,
