rigid tank contains air at 40°C that is being stirred by a paddle wheel. The paddle wheel does 250 kJ of work on the air (R=0.287 kJ/kgK, cv=0.718 kJ/kgK, and cp=1.005 kJ/kgK). It is observed that the temperature of the air remains constant during this process as a result of heat transfer between the system and the surroundings at 30°C. The entropy generation for this process is
