Answer to Question #293172 in Mechanical Engineering for Momi

Question

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 the law

pv1.3=constant, and is finally heated at constant volume back to the initial conditions. The

work done in the constant pressure process is 515 Nm and the mass of the fluid present is

0.2 kg. Calculate the net work done on or by the fluid in the cycle and sketch the cycle on

a p-v diagram
