Two thermally insulated vessels are connected by a narrow tube fitted with a valve that is initially closed as shown in the figure below. One vessel of volume V1 = 15.6 L, contains oxygen at a temperature of T1 = 295 K and a pressure of P1 = 1.76 atm. The other vessel of volume V2 = 23.0 L contains oxygen at a temperature of T2 = 435 K and a pressure of P2 = 2.10 atm. When the valve...

(14marks) Problem (4) Two tanks are connected by a valve. One tank contains 3 kg of carbon monoxide (C0) gas at contains 8 kg of the same gas at 27 °C and 120 KPa. The valve is opened and the gases are allowed to mix while receiving energy by heat transfer from the surroundings. The final equilibrium temperature is 42 °C. Determine: 97 °C and 60 KPa. The other tank (a)The final pressure. (b)The heat transfer for the process...
An insulated tank has two compartments connected by a membrane. Initially, one compartment contains 0.4 kmol of CO2 at 150 ̊C, 600kPa and the other contains 0.3 kmol of N2 at 100 ̊C, 300kPa. The valve...
An insulated tank has two compartments connected by a membrane. Initially, one compartment contains 0.4 kmol of CO2 at 150 ̊C, 600kPa and the other contains 0.3 kmol of N2 at 100 ̊C, 300kPa. The valve is opened and the gases are allowed to mix until equilibrium is achieved. Determine the final temperature, pressure, and the amount of entropy generation.

A two-chambered tank is connected to a high pressure pipeline containing air. The bottom chamber of the tank contains air that is initially at 450 kPa and 300 K due to the force of an adiabatic, weighted piston (piston face area is 1.5 square meters). The piston separates the top and bottom chambers. The top chamber and bottom chamber each have an initial volume of 2.0 cubic meters. Other conditions and properties are shown in the attached figure. The valve...

Problem 3-2 A rigid, well-insulated tank consists of two compartments eparated by a valve, one being twice the volume of the other. Initially, the smaller compartment contains 10 kg of nitrogen at 6 bar and 100°C, while the larger one is evacuated. The valve is opened and the gas expands to fill the total volume, eventually achieving an equilibrium state. Calculate: a) The final temperature, in K. b) The final pressure, in bar, c) The total exergy destroyed, in kJ...

Asking for Q3,4,5,6.
Mixing Gases Consider two containers, . Both have volume 0.1 m3, and pressure 106 pa One contains monatomic (3 degrees of freedom) He at T 128 K and One contains diatomic (5 degrees of freedom) N2 at T- 258 K. A valve is opened allowing these two gases to mix. They are kept thermally isolated from the outside You can treat them as i deal gases. 1) What is the change in internal energy under this process?...
