A piston cylinder assembly contains 19kg of water that executes four processes in series: • Process 1-->2: Constant pressure cooling from P1=20bar and T1=360°C to saturated vapor • Process 2-->3: Constant volume cooling to P3=5bar • Process 3-->4: Constant pressure heating to v4=0.5644m3/kg • Process 4-->5: Polytropic process following Pv =constant until P5=20bar A. Considering the water as the system, is the system best described as open, closed, or isolated? WHY? B. Sketch the series of processes on PT, Pv, and Tv diagrams. Include values on the P, T, and v axes. Indicate states with filled dots, processes with solid lines, and directions with arrows. C. Does this complete series of processes represent a thermodynamics cycle? EXPLAIN your reasoning. Answer parts A and C in the box below; upload part B as part of your response PDF.

A fluid is heated reversibly at a constant pressure of 1.05 bar until it has a specific volume of 0.1 m'/kg. It is then compressed reversibly according to a law pu = constant to a pressure of 4.2 bar, then allowed to expand reversibly according to a law pel.- constant, and is finally heated at constant volume back to the initial conditions. The work done in the constant pressure process is -515 N m, and the mass of fluid present is 0.2 kg. Calculate the net work of the cycle and sketch the cycle on a p-v diagram.
