A piston-cylinder device op- erates 1 kg of fluid at 20 atm. pressure. The initial volume is 0.04 m. The fluid is allowed to expand reversibly following a process pV1.45 = constant so that the volume becomes double. The fluid is then cooled at constant pressure until the piston comes back to the original position. Keeping the piston unaltered, heat is added reversibly to restore it to the initial pressure. Calculate the work done in the cycle. pV1.45-C 3.

Solve  this 

1 A piston-cylinder device op- erates 1 kg of fluid at 20 atm. pressure. The initial volume is 0.04 m?. The fluid is allowed to expand reversibly following a process pV.45 = constant so that the volume becomes double. The fluid is then cooled at constant pressure until the piston comes back to the original position. Keeping the piston unaltered, heat is added reversibly to restore it to the initial pressure. Calculate the work done in the cycle. pv1.45-C -2 V. 3.
