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 tank contains an ideal gas at 40'C that is being stirred by a paddle wheel. The paddle wheel does 200 kJ of work on the ideal gas. It is observed that the temperature of the ideal gas remains constant during this process as a result of heat transfer between the system and the surroundings at 30°C. Determine the entropy change of the ideal gas. Heat Ideal gas 40°C 30°C The entropy change of the ideal gas is JK

7. The chemical engineering lab contains a 1.5 m rigid tank installed with a paddle wheel. Suppose this tank is filled with 2.7 kg of carbon dioxide at 100 kPa, and that paddle-wheel work is done on the system until the pressure rises to 150 kPa. Determine the entropy change of the system during this process (kJ/K). You may assume that the tank is well-insulated, and that CO2 is an ideal gas with constant specific heats at RT.

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...
