Two rigid tanks are separated by a thin partition. Tank A holds 1.1 kg of R-134a at 800 kPa and 60∘∘C. Tank B holds 1.7 kg of R-134a at 10∘∘C with a quality of 21%. When the partition is removed the two sides mix and reach a state of thermal and mechanical equilibrium. The final pressure at this state is 500 kPa.
What is the quality of the refrigerant at this final state?
What is the amount of heat transferred to the system? (Use the sign convention discussed in class; i.e. heat in is positive, heat out is negative.)

A rigid tank contains a partition that divides the tank into two sections, each having a volume of 2 ft3 . The left side contains 1.5 lbm of refrigerant R-134a at a pressure of 50 psia, and the right side contains 4 lbm of refrigerant R-134a at 30 psia. The partition is removed and the contents are allowed to mix. Heat transfer occurs with the surroundings until the entire tank contents reach a new equilibrium temperature of 60 °F. For...

A tank whose volume is unknown is divided into two parts by a partition. One side of the tank contains 0.017 m of refrigerant-134a that is a saturated liquid at 0.95 MPa, while the other side is evacuated. The partition is now removed, and the refrigerant fills the entire tank. If the final state of the refrigerant is 20°C and 400 kPa, determine the volume of the tank. Round your answer to three decimal places. VFI R-134a V 0.017 m...

1- A fixed mass rigid tank is filled with Refrigerant-134a. Assuming initially, R-134a is under 160 psia and saturated condition (quality, x, = 1.0). The volume of tank is 20 ft. Then it went through a process until the final pressure, P, reduced to 50 psia, and the heat transfer occurred during this process. Determine (a) the final temperature, (b) the amount of R-134a been condensed, (c) the net heat transfer. (15 points)

(4 points) A-C line Liquid R-134a A rigid container containing 6.8 kg of saturated liquid R-134a at 26°C is used to fill an air- conditioning system. A valve is opened and allows liquid R-134a to escape the tank into the A-C line until only 0.85 kg of R-134a remains in the tank, at which point the valve is closed.

Two rigid tanks are connected by a valve.The left tank with a volume of 1.8m3 contains air at 28.1 C and 575 kPa while the right tank contains 4.2 kg of air at 33.3C and 410 kPa. Now the valve is opened and the air is allowed to mix until the system reaches thermal equilibrium with the surroundings at 13.8C. Determine the volume of the right tank and the final air pressure.

A rigid tank is divided into two equal parts by a partition. One part of the tank contains 3.0 kg of compressed liquid water at 400 kPa and 50°C, while the other part is evacuated. The partition is now removed and the water expands to fill the entire tank. Determine the entropy change of the water during this process, if the pressure in the tank is 30 kPa.
