A rigid tank contains air at 50°C that is being stirred by a paddle wheel. The paddle wheel does 350 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 air remains constant during this process as a result of heat transfer between the system and the surroundings at 22°C. The entropy generation for this process is Lütfen birini seçin: a. 1.409 kJ/K b. 1.387 kJ/K C. 0.984 kJ/K d. 1.186 kJ/K e. 1.320 kJ/K
