3. Similar to 13-42 A rigid tank that contains 1.57 kg of N2 at 25°C and 550 kPa is connected to another rigid tank that contains 3.71 kg of O2 at 25°C and 170 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

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...

1. A rigid (constant volume) tank sealed by a valve initially contains 100 kg of air at a pressure of 100 kPa and 300 K. At time t = 0, the valve for the air tank is opened in a controlled manner and air leaks out isothermally (constant temperature) of the tank at a constant mass flow rate of 1 kg/s. The valve is closed after 75 seconds. Answer the following questions: Assuming air is an ideal gas, what is...

1. (10 pts) A 10 m® rigid storage tank contains oxygen gas (R = 0.2598 kJ/kg.K, Cp = 0.918 kJ/kg.K, cv = 0.658 kJ/kg.K). The tank is initially 200 kPa and 600° It is cooled to 25°C in 35 minutes. Determine: 1. (3 pts) The mass of oxygen in the tank, in kg. 2. (3 pts) The final pressure in the tank, in kPa. 3. (4 pts) The rate of heat transfer from the oxygen, in kW.

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.

Problem 5: A rigid tank contains 3.52 kg of an ideal gas. The volume of the tank is V 1.20 m3 and initially the gas is at a pressure of Pi 225 kPa. The tank is charged by adding 0.74 kg of the same gas at which point the new pressure is 450 kPa and the new temperature is 153.94 °C. Determine the gas constant, R, a possible identity of the gas, the original temperature, T, the original density, pi,...
A 9.8 m3 rigid tank contains steam at 220°C.
Pressure in tank = 2320 kPaQuality of saturated mixture = 0.0269A 9.8 m3 rigid tank contains steam at 220°C. One-third of the volume is in the liquid phase and the rest is in the vapor form. Determine the density of the mixture. (Round the final answer to one decimal place.) (You must provide an answer before moving on to the next part.) The saturated water-temperature table (in Sl units) is given below.The density of the mixture is _______ kg/m3
