The UTC chemical engineering lab contains a 1.5 m3 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 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

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, insulated tank fitted with a paddle wheel is filled with water, initially a two-phase liquid-vapor mixture at 200 kPa, consisting of 0.04 kg of saturated liquid and 0.04 kg of saturated vapor. The tank contents are stirred by the paddle wheel until all of the water is saturated vapor at a pressure greater than 138 kPa. Kinetic and potential energy effects are negligible. For the water, determine...
