2 kg Water in a vertical piston cylinder arrangement, is initially at saturated liquid state at 3 bar. It is heated and undergoes constant pressure expansion to a state of saturated vapor. What is the work done by the piston cylinder arrangement to the environment? Neglect the mass of the piston, piston friction, kinetic and potential energy changes. Hint: this is a closed system problem, remember control volume boundary work concept. What is the heat transfer into the water?

Problem 3.052 A piston–cylinder assembly contains 2 lb of water, initially at 100 lbf/in.2 and 450°F. The water undergoes two processes in series: a constant-pressure process followed by a constant volume process. At the end of the constant-volume process, the temperature is 300°F and the water is a two-phase liquid–vapor mixture with a quality of 40%. Neglect kinetic and potential energy effects. Determine the work and heat transfer for each process, all in Btu.

One and one-half pounds of water within a piston-cylinder assembly execute a Carnot power cycle. During isothermal expansion, the water is heated at 500 degree F from saturated liquid to saturated vapor. The vapor then expands adiabatically to a temperature of 100 degree F and a quality of 70.38%. Sketch the cycle on p-v coordinates. Evaluate the heat transfer and work for each process, in Btu. Evaluate the thermal efficiency.

Please answer fast
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.

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.
