Two rigid tanks filled with water are connected by a valve. Tank A has a pressure of 40.9 psia, a specific volume of 17.52 ft3lbm, and a volume of 22.2 ft3. Tank B contains 5 lbm of water at 80 psia and 443∘F. What is the volume of tank B? ft3 The valve is opened and the two tanks reach an equilibrium state. (Assume the valve does not occupy any additional volume.) What is the specific volume of the water in its final state? ft3lbm

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.

Two rigid tanks are connected by a valve. Initially, one tank contains 10 mº of helium (He) gas at 220 kPa, 40°C? The other tank initially contains 4.0 R of neon (Ne) gas at 150 kPa, sot. Now the valve is opened, allowing the two gases to mix with each other. Heat transfer occurs during the mixing process. The final equilibrium temperature is 44'C. The specific heats of monatomic gases are independent of temperature. Determine: (a) the final volume of...

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...

Two well insulated tanks of oxygen are connected together. The first tank has a volume of 16.8 L and starts off with the gas at pressure 1.75 atm and a temperature of 300K. The second tank has a volume of 22.4, but its gas starts off with a pressure of 2.25 atm at a temperature of 450K. When the valve is opened between the two tanks, what is the final temperature and pressure of the combined gas?

An insulated, rigid tank that is initially evacuated is connected by a valve to a nitrogen supply line. The nitrogen in the line flows at 30°C and 80 kPa. The valve is then opened and nitrogen flows into the tank until the pressure reaches 80 kPa; at which point the valve is closed. Using constant specific heats at room temperature (Cp = 1.039 kJ/kgK, Cv = 0.743 kJ/kgK, k. = 1.3984), determine the final temperature of the nitrogen in the...

2. Consider a process in which two tanks A and B are connected by a valve. Tank A, which is insulated, has a volume of 600 liters and contains steam at 1.4 MPa, 300°C. Tank B, which is uninsulated, has a volume of 300 liters and contains steam at 200 kPa, 200°C. The valve connecting the two tanks is now opened and steam flows from A to B until the temperature in A reaches 250°C, at which time the valve...

Two rigid vessels, connected through a valve which is originally closed, are submerged in a constant temperature bath at 200 °C. Initially, vessel A which has a volume of 1.1 m3 contains 10.0 kg of H20. This is State (A,1). Vessel B which has a volume of 20.62 m2 is evacuated. This is State (B,1). After the valve has been opened, the H2O is distributed between the two vessels. In this state, the pressures in both vessels are the same....
