4 (30 points). A rigid tank that is initially evacuated is connected through a valve toa supply line that carries helium at 1 MPa and 300 K. Now the valve is opened, and helium is allowed to flow slowly intothe tank until the pressure reaches IMPa P2). The final temperature and mass of the helium gas in the tank are: T2 300 K and m2 1 kg. Determine the direction (Is heat transferred to or from the tank?) and amount...

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 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 is closed and it is found that p2-5 bars (500 kPa). Find (a) the state of the...

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...

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...

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 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...

A 2-m rigid insulated tank initially containing saturated water vapor at 1.2 MPa is connected through a valve to a supply line that carries steam at 400 °C. Now, the valve is opened, and steam is allowed to flow slowly into the tank until the pressure in the tank rises to 2.5 MPa. At this instant, the tank temperature is measured to be 350 °C. Determine a) the mass of the steam that has entered the tank from the supply...

(1 point) A rigid, insulated 0.43 m tank initially contains saturated water liquid at 362 kPa. The tank is connected to a steam pipe line carrying steam at 1.53 MPa and 305 °C through a valve. When the valve is opened, steam enters the tank from the pipe. When the valve is closed, the tank is filled with a saturated vapor with a pressure of 0.8 MPa. How much mass was added to the tank during this process?

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...
