Water in a piston-cylinder assembly is initially at a pressure of 10 bar and a temperature of 500 C. The water is cooled and compressed at constant pressure until it becomes a saturated vapor. The water is then cooled at a constant volume until it reaches a temperature of 150 C.
a) Sketch both processes on T-v and p-v diagrams (v here is specific volume).
b) Determine the total work for the overall processes.
c) Determine the heat transfer for the overall process.

Water vapor initially at 10 bara and 400°C is contained within a piston-cylinder assembly. The water is cooled at constant volume until its temperature is 150°C. The water is then condensed isothermally to saturated liquid. Sketch the process in T-v coordinates. Clearly label the three states. For the water as the system, (a) write the symbolic equation for the specific work (and simplify), w; and (b) evaluate the specific work, in kJ/kg.

Referring to the figure shown below, water contained in a piston–cylinder assembly, initially at 1.5 bar and a quality of 60%, is heated at constant pressure until the piston hits the stops. Heating then continues until the water is saturated vapor. The initial height, L1, is 0.05 m and the change in height, L2, is 0.03 m. For the overall process of the water, evaluate the work and heat transfer, each in kJ/kg. Kinetic and potential effects are negligible.

Saturated liquid at a pressure 200 bar is contained in a piston-cylinder system at a volume of V 0.01 m3. The system undergoes a two-step process, which is the following: (1) A constant volume cooling process to a temperature of 200°C; and (2) A constant pressure expansion to 320°C following process 1. Determine the work and heat transfer for both processes and show the processes on p-v and t-v diagrams.
