A tank contains air at 0.25 bars and 300K. The volume of the tank is 3 m3. A crack on the tank causes leakage from the surroundings at 1.25 bars and 350K. What is the final temperature in the tank after equilibrium is reached and how much air leaked in during the process?

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...

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...

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.

A piston cylinder device contains air with a volume of 0.05 m3 at 25oC and 100 kPa pressure. The gas is now compressed to a final temperature of 95oC at 250 kPa. This compression is polytropic and follows PVn=constant. a. Determine how much boundary work was added to the gas [in kJ] b. How much heat was added or removed from this system during this process? [in kJ]

Arigid tank of volume 0.5 m3 is connected to a piston-cylinder assembly by a valve as shown in the diagram below. Both vessels contain pure water. They are immersed in a constant- temperature bath at 200°C and 600 kPa. Consider the tank and the piston-cylinder as- sembly as the system and the constant-temperature bath as the surroundings. Initially the valve is closed, and both units are in equilibrium with the surroundings (the bath). The rigid tank contains saturated water with...
