A rigid tank initially contains 0.32 kg steam at 4 MPa, superheated by 350°C. Now the steam loses heat to the surroundings and the cooling of tank continues until the cylinder contains water at 90°C. Determine; (a) the final pressure and the quality (if mixture), (b) the boundary work, (c) the amount of heat transfer (d) and the total entropy generation if the Tsur=20 °C.

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 1-mº rigid tank contains 100 kg R-134a at a temperature of 16 °C. A valve on top of the tank is opened, and saturated vapor is allowed to escape through a throttle to a collector system at 100 kPa. During the process the temperature inside the tank remains at 16 °C by heat transfer from the 20 °C surroundings. The valve is closed when no more liquid remains inside the tank. Calculate the heat transfer to the tank and...
