Question

Unit mass of a certain fluid is contained in a cylinder at an initial pressure of 20bar. The fluid is allowed to expand reversibly behind a piston according to a law pv = constant until the volume is double. The fluid is then cooled reversibly at constant pressure until the piston regained its original position; heat is then supplied reversibly with the piston firmly locked in position until the pressure rises to the original value of 20bar. Calculate the net work done by the fluid, for an initial volume of 0.05m3

Answer 1

unit mass of a certain fluid is contained in a cylindrical pressure of 20bar.
