Two identical piston cylinder devices A and B both contain 1 kg of saturated water mixture at the quality of x = 0.5 at the pressure of p = 100 kPa. Both systems are heated until the quality of the systems reach to x - 0.8. However, the system in cylinder A undergoes an internally irreversible heating process but the heating in cylinder B takes place in a reversible manner. At the end of the processes when thermodynamic equilibrium is reached both systems have the same pressure of p 100 kPa. a) What can be said about the entropy change AS of the systems A and B during these processes ? Compare them in terms of magnitude. Please explain your answer. (You do not need to calculate the exact number for the entropy change) b) Compare the two processes in terms of entropy generation. If you can express the magnitude of Sgen for any of those processes please do.

A and B containers (fixed volume) are connected together by a valve. Tank A contains 400 kPa and 0.3 m3 refrigerant 134a at 60% dryness. Tank B contains 0.5 m3 of refrigerant 134a at 240 kPa pressure and 100 oC temperature. Then the valve is opened and the system reaches 280 kPa equilibrium pressure. Calculate the final temperature.
Question 1 (a) In the thermodynamic laboratory, student Ali prepared a piston-cylinder device which contains refrigerant-134a at 1000 kPa and 50°C. The mass of the refrigerant is 6 kg. The next step of the experiment involves cooling the refrigerant at constant pressure until its state become liquid at 24°C. Show the process on T-v diagram and determine the heat loss from the system.
4. Ab.5 m' rigid tank contains refrigerant-134a initially at 200 kPa and 40 percent quality. Heat is now transferred to the refrigerant until the pressure reaches 800 kPa. Determine (a) the mass of the refrigerant in the tank and (b) the amount of heat transferred. Also, show the process on a P-v diagram with respect to saturation lines. [12.3 kg, 2956.2
A mass of 5.1 kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder at 100 kPa. Initially, 2.9 kg of the water is in the liquid phase and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 300 kPa. Heat transfer continues until the total volume increases by 22 percent. Determine:a) the initial temperature (oC),b) the final temperature (oC),c) the specific volume of water when the piston first starts moving (m3/kg), andd) the work done during this process (kJ).
