Question

Air is contained in a variable load piston-cylinder device equipped with a paddle wheel. Initially air is at 500 kPa and 27 degrees C. The paddle wheel is turned by an external electric motor until 20 kJ/kg of work has been transferred to the air. During this process, heat is transferred to maintain a constant air temperature while allowing gas volume to double. (Hint: The pressure varies during the process). a.) Determine the boundary work per unit mass during the process (KJ/Kg) b.) Calculate the required amount of heat transfer (KJ/Kg)
