The pressure of the gas inside the piston is 110 kPa and the spring is compressed by 0.1 m. The cylinder has a cross-sectional area of 1 m^2 and the piston mass is 1000 kg. Water (density= 1000 kg/m3) is slowly poured onto the piston to a depth is 5 m. The piston seal prevents any water from entering the gas-filled portion of the cylinder. During this process, the 10 kJ of work is provided to the paddle stirrer. Required:
Show that if that the piston-cylinder system contains 4 kg of ARGON and the piston is initially 5 m above the bottom of the cylinder, then heat removal of 1225.32 kJ is required to maintain a constant pressure for the process.
