Question

5. A process engineer is assigned to design a typical thermodynamic system comprising of adiabatic expansion process and isobaric process in a piston-cylinder arrangement system. In a well-insulated piston-cylinder system, where 0.2m3 of atmospheric air at 400 kPa and 403 K is sucked into the engine cylinder which undergoes a reversible adiabatic expansion process till the pressure falls to 102 kPa. The atmospheric pressure is then heated at constant pressure till the heat added reaches to 72.5 kJ. Determine the following parameters with the aid of a neat pV diagram: a). The heat transfer (in J & kJ) during the adiabatic expansion process
b). The work done (in J & kJ) during the adiabatic expansion process
c). The work done (in J & kJ) during the isobaric process
d). The total work done (in J & kJ).
