A rigid tank whose volume is 3 m3, initially containing air at 1 bar, 295 K, is connected by a valve to a large vessel holding air at 6 bar, 295 K. The valve is opened only as long as required to fill the tank with air to a pressure of 6 bar and a temperature of 320 K. Assuming the ideal gas model for the air determine the heat transfer between the tank contents and the surroundings, in kl....

PROBLEM 2 (35 points). An insulated, rigid tank whose volume is 0.5 m3 is connected by a valve to a large vessel holding steam at 60 bar, and 440°C. The tank is initially evacuated. The valve is open only as long as required to fill the tank with stream to a pressure of 40 bar. As this occurs, a paddle wheel adds 260 kJ per kg of work to the tank (where the kg mass for this work represents the...

A rigid tank, whose volume is 0.5 m3, initially
containing ammonia at 20oC, 1.5 bar, is connected by a
valve to a large supply line carrying ammonia at 12 bar,
60oC. The valve is opened only long enough to fill the
tank with additional ammonia, bringing the total mass of ammonia in
the tank to 143.36 kg. Finally, the tank holds a two-phase
liquid-vapor mixture at 20oC. Ignoring kinetic and
potential energy effects, determine the heat transfer between the
tank...

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...

2. (10 points) Assume that you have rigid container with a volume of 0.75 m? The container is initially evacuated (empty). Unfortunately, a tiny hole develops in the side of the container, and air from the surroundings leaks in. The surrounding air is at 100 kPa and 25°C. The air leaks in until the pressure in the container is the same as the pressure of the surrounding air. The process occurs slowly enough that heat transfer between the container and...
