1 kg of saturated steam at 1000 kPa is in a piston-cylinder and the massless cylinder is held in place by pins. The pins are removed and the system suddenly and adiabatically expands to 5x its original volume before the piston hits a pair of upper pins. The expansion takes place against an atmosphere is 60 kPa. What is the final specific internal energy of the system? The answer will be in kJ/kg.

A piston–cylinder device contains 5 kg of steam at 100°C with a quality of 50 percent. This steam undergoes two processes as follows: (1-2) Heat is transferred to the steam in a reversible manner while the temperature is held constant until the steam exists as a saturated vapor.(2-3) The steam expands in an adiabatic, reversible process until the pressure is 15 kPa. Sketch these processes with respect to the saturation lines on a single TS diagram and determine the heat...
