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...

SP04 A rigid, poorly insulated tank with a volume of V1.0 m3 initially contains a saturated water vapor (quality of 1.0) at a pressure of 3 bars (300 kPa). The tank is connected to a supply line containing steam at a pressure of pL- 10 bars (1000 kPa) and a temperature of TL 500°C. The valve is opened and 2.0 kg of steam enters the rigid tank, after which the valve is closed. The pressure is measured after the valve...

An insulated 1.7 m3 rigid tank contains air at 500 kPa and 50oC. A valve connected to the tank is now opened and air is allowed to escape until the pressure inside drops to 200 kPa. The air temperature during this process is maintained constant by an electric resistance heater placed in the tank. a. Determine the mass of air initially, m1 in kg. b. How much air escaped from the tank, mout in kg. c. Determine the electrical work...

4. A 1.5-m rigid tank is initially empty. Refrigerant (R-134a) in the supply line at 750kPa and 20°C is connected to the well-insulated tank through a valve. The valve is opened, and R-134a enters the tank until the pressure in the tank reaches the pressure of 500 kPa, at which point the valve is closed. (a) Write the assumptions. (b) Show the 1" law of thermodynamics with a control volume. (c) Determine the final temperature in the tank. (d) Determine...

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...
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 rigid, insulated tank contains a certain amount of argon at room temperature 25o C and 500 kPa. Now the valve is opened and the argon is allowed to vent into atmosphere until 80% argon remains in the tank. Determine the final temperature of the argon in the tank. It is assumed the argon leaving the tank is at room temperature.
