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...

Two thoroughly insulated rigid tanks are joined by a valve. One of them contains N2 (2 kg, 27 °C, 500 kPa, molar mass = 28.013 g/mol, Cv = 0.743 kJ/kg.K) while the other contains O2 (6 kg, 40 °C, 225 kPa, molar mass = - 31.999 g/mol, Cv = 0.658 kJ/kg.K). If the connecting valve is fully opened, determine the equilibrium mixture temperature and pressure. Use RN2 = 0.2968 kJ/kg.K and Ro2 = 0.2598 kJ/kg.K.

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...
