1 kg of water executes a cycle in a piston cylinder assembly, starting out at high T (300 deg C) and high P (15 MPa). The piston is released and the system expands rapidly in a process that can be treated as adiabatic. At the end of the expansion, the water in the cylinder is at atmospheric pressure (101.3 kPa) and the volume has increased by a factor of 580. The piston is then held rigidly in place, and the system is heated until the contents are saturated vapor. The system next expands reversibly to 1 m3 at constant pressure. Finally, the system is returned to its initial state in a compression process with heat rejection requiring 1 MJ of work input. Is the cycle a power cycle? Quantify the cycle performance (use an appropriate metric depending on the cycle type).
