6.50 m A closed, rigid tank contains 5 kg of air initially at 300 K, 1 bar. As illustrated in Fig. P6.50, the tank is in contact with a thermal reservoir at 600 K and heat transfer occurs at the boundary where the temperature is 600 K. A stirring rod transfers 600 kJ of energy to the air. The final temperature is 600 K. The air can be modeled as an ideal gas with cy = 0.733 kJ/kg . K...

A closed, rigid tank fitted with a paddle wheel contains 1.6 kg of air, initially at 200oC, 1 bar. During an interval of 10 minutes, the paddle wheel transfers energy to the air at a rate of 1 kW. During this time interval, the air also receives energy by heat transfer at a rate of 0.5 kW. These are the only energy transfers. Assume the ideal gas model for the air, and no overall changes in kinetic or potential energy....

A rigid copper tank, initially containing 1 m^3 of air at 295K, 5 bar, is connected by a valve to a large supply line carrying air at 295K, 15 bar. The valve is opened only as long as required to fill the tank with air to a pressure of 15 bar. Finally, the air in the tank is at 310 K. The copper tank, which has a mass of 20 kg, is at the same temperature as the air in...

Problem 6.030 SI Air is compressed adiabatically in a piston-cylinder assembly from 1 bar, 300 K to 4 bar, 600 K. The air can be modeled as an ideal gas and kinetic and potential energy effects are negligible. Determine the amount of entropy produced, in kJ/K per kg of air, for the compression. What is the minimum theoretical work input, in kj per kg of air, for an adiabatic compression from the given initial state to a final pressure of...
