Assignment 2
Unit mass of a certain fluid is contained in a cylinder at an initial pressure
of 20 bar. The fluid is allowed to expand reversibly behind a piston
according to a law pV2 = constant until the volume is doubled. The fluid is
then cooled reversibly at constant pressure until the piston regains its
original position; heat is then supplied reversibly with the piston firmly
locked in position until the pressure rises to the original value of 20 bar.
Calculate the net work done by the fluid, for an initial volume of 0.05 m 3•
