_A constant hydraulic pressure on the back face of the piston maintains a cylinder pressure of 12 MPa. Initially, the water is at 750°C, and the volume is 120 L. The water is now cooled and H.E. 13 WHE condensed to saturated liquid. The heat released during this process is the Q supply to a cyclic heat engine that in turn rejects heat to the ambient at 35°C. If the overall process is reversible, what is the net-work output of the heat engine?
