Question 18 1 pts Problems 18-20 are based on the following description An insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains 10 kg of an ideal gas with molar mass M-16 kg/kmol, a pressure of 330 kPa, and a temperature of 50 oC. The other part is evacuated. The partition is now removed and the gas fills the entire tank. (R. - 8.31447 kJ/kmol.K) The expansion work in kJ is closer to:...

An insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains 15 kg of water vapor with steam quality 20% at 20 bar and the other part is evacuated. The partition is removed, and the water vapor expands into the entire tank.a) Determine the final temperature and pressure using higher accuracy calculation. b) Recalculate (a) by assuming the gas behave as ideal gas

Problem 3. (10 points) A closed and insulated rigid tank (perfectly insulated) is initially divided into halves by a separator. On one side of the separator is 1 m of air at 300 K, 2 bar. On the other side is 1 m of air at 500 K, 1 bar. The separator is removed, and the air from the two sides mixes and reaches equilibrium state Please treat the air as ideal gas with cp-1.001 kJ/kg K and c0.714 kJ/kg...

Thermodynamics 1. (correct answer: 0.080595 ) Initially, an insulated rigid tank contains 20 kg of water at 29.5oC and 101 kPa. The tank also contains a 4.86 kg aluminum block at 93.2oC. Using constant specific heats evaluated at 300 K, determine the total entropy production (kJ/K) after an hour assuming thermal equilibrium is achieved. 2. Correct Answer: 8.0087 ± 0.1% Steam at 1 MPa, 593.2oC, expands in a turbine to 0.01 MPa. If the process is isentropic, find the specific...

The mass of an insulated 0.6 m3 steel tank is 20 kg. The steel has a specific heat of 0.46 kJ/kg K. The tank is placed in a room where the surrounding air is 21°C and 101.3 kPa. After the tank is evacuated to 7 kPa and 21°C, a valve is suddenly opened, allowing the tank to fill with room air. The air enters the tank in a well mixed, turbulent condition. Find the air temperature inside the tank after...

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...
