PROBLEM #3. [30 POINTS! Two tanks are connected by a valve. One tank contains 2 kg of carbon monoxide gas at 77°C and 0.7 bars. The other tank holds 8 kg of the same gas at 27°C and 1.2 bars The valve is opened and the gases are allowed to mix. The final equilibrium temperature is 42°C. Using the ideal gas model, determine the final equilibrium pressure, in bars. Solution:
Two rigid tanks are connected by a valve. Initially, one tank contains 10 mº of helium...
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...

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 that contains 2.4 kg of N2 at 25°C and 550 kPa is connected to another rigid tank that contains 4.4 kg of O2 at 25°C and 150 kPa. The valve connecting the two tanks is opened, and the two gases are allowed to mix. If the final mixture temperature is 25°C, determine the volume of each tank and the final mixture pressure. The gas constants of N2 and O2 are 0.2968 and 0.2598 kPa.m3/kg.K, respectively. The universal...

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...

A 2.2-m3 rigid tank initially contains air at 100 kPa and 22°C. The tank is connected to a supply line through a valve. Air is flowing in the supply line at 600 kPa and 22°C. The valve is opened, and air is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. A thermometer placed in the tank indicates that the air temperature at the final state is...

A 1-mº rigid tank contains 100 kg R-134a at a temperature of 16 °C. A valve on top of the tank is opened, and saturated vapor is allowed to escape through a throttle to a collector system at 100 kPa. During the process the temperature inside the tank remains at 16 °C by heat transfer from the 20 °C surroundings. The valve is closed when no more liquid remains inside the tank. Calculate the heat transfer to the tank and...
