Air is contained in a piston cylinder device that has a
resistance heater inside. The atmosphere exerts a pressure of 100
kpa on the piston of which it has a mass of 45 kg and a transverse
area of 0.9 m². An electric current passes through the resistance
of the air volume slowly increases by 0.45 m³ while the pressure
remains constant. The mass of the air is 0.27 kg and its specific
internal energy increases 42 kJ / kg,...

Consider a piston-cylinder device (system) that contains 0.06 m3 of air at 300 kPa and 125 ̊C. (a) If the volume of air in the device increases to 0.15 m3 while the pressure remains constant, determine the work done by the system during the process. (b) If as a result of heat transfer to the surrounding, the pressure and temperature in the device drop to 240 kPa and 55 ̊C, respectively, and the piston is held such that the volume...

4) The work produced by a piston-cylinder device depends on the pressure inside the cylinder and the amount the piston moves, resulting in a change in volume inside the cylinder. Mathematically In order to integrate this equation, we need to understand how the pressure changes with the volume. We can model most combustion gases as air and assume that they follow the ideal gas law PV- nRT where P- pressure, kPa, volume, m n- number of...
