Please help me with this Thermal problem. Thanks Problem 1. Consider a well-insulated tank with constant...
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...
Please help solving it Constant V 1 2 3 A tank with a constant volume of 3.81 m2 contains 12.1 moles of a monatomic ideal gas. The gas is initially at a temperature of 300 K. An electric heater is used to transfer 45200 J of energy into the gas. It may help you to recall that Cv -12.47 J/K/mole for a monatomic ideal gas, and that the number of gas molecules is equal to Avagadros number (6.022 x 1023)...
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...
4) Volume 2.5 m^3 air in a rigid tank with initial pressure 100 kPa and temperature 25°C There. It is applied to the tank feed line by a valve. Pressure of air flowing through the supply line 600 kPa and temperature is 25°C. By opening the valve, the pressure of the air in the tank is air entering the tank until it is equal to the pressure of the air It is closed. A thermometer placed in the tank lasts...
Problem No. 3 (20 Points) The density p of the air contained in a pressurized tank is to be calculated by measuring the pressure P and the temperature T inside the tank. Density of the air in the tank calculated is to be from the ideal gas law: P = PRT Where R = 287 kg*K for air. The temperature is to be measured with uncertainty of 5 K. The pressure is to be measured with uncertainty of 2.5 (10)...
Thermodynamics 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: O 1678 O 725...

1.Argon contained in a closed, rigid tank, initially at 62.3°C, 3.9 bar, and a volume of 4.2 m3, is heated to a final pressure of 9.4 bar. Assuming the ideal gas model with k = 1.6 for the argon, determine the heat transfer, in kJ. 2.Water vapor contained in a piston–cylinder assembly undergoes an isothermal expansion at 223°C from a pressure of 5.4 bar to a pressure of 1.9 bar. Evaluate the work, in kJ/kg. 3.A mass of 4 kilograms...
well insulated tank fitted with an electrical resistor of negligible mass holds 2 kg of nirtogen (N2) initially at 300 K, 1 bar. over a period of 10 minutes, electricity is provided to the resistor at a constant voltage of 120 volts and with a constant current of 1 ampere. assuming ideal gas behavior, determine the nirtogen's final temperature, in K, and the final pressure, in bar.
can you help me with this question please if there's a vacuum above the piston what is the combined weight of pain and masses in Newtons Remove Looking pin 50 cm 1.0 atm 20°C 100 cm 3.0 am WWW 1. Start 2. Heat to 3 atm. 3. Remove pin. Continue heating to 100 cm 4. Insert pin. Remove mass The figure shows a sample of N2 gas covered by a movable piston, first in its initial state and then undergoing...
