In our tutorials, we solved this problem where air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. Initially, air is at 400 kPa and 17C. The paddle wheel is now turned by an external electric motor until 75 kJ/kg of work has been transferred to air. During this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. We calculated the required amount of heat transfer to be 16.44 kJ/kg. Assume the ambient temperature is at 25C and the ambient pressure is at 100 kPa. Based on this, choose from below on the estimated value of the generated entropy for this system (Sgen, sys) and the feasibility of the process. Air 400 kPa 17C Wh a) Sgen, sys= 0.2586 kJ/kg-K, the process is not thermodynamically feasible. b) Sgen, sys= 0.2586 kJ/kg-K, the process is thermodynamically feasible. c) Sgen, sys= 0.2516 kJ/kg-K, the process is thermodynamically feasible. d) Sgen, sys = 0.2516 kJ/kg-K, the process is thermodynamically feasible.
