3.111 Air contained in a piston-cylinder assembly contains air, initially at 2 bar, 300 K and a volume of 2 m^3. The air undergoes a process to a state where pressure is 1 bar, during which the pressure-volume relationship is PV=constant. Assuming ideal gas behavior for air, determine the mass of the air, in kg and the work and heat transfer, each in KJ.

Question 1 A piston-cylinder assembly contains 3.2 kg of water at 211.9oC and 3 bar. The water is compressed to a saturated vapor state where the pressure is 51.5 bar. During compression, there is a heat transfer of energy from the water to its surroundings having a magnitude of 230 kJ. Neglecting changes in kinetic energy and potential energy, determine the work, in kJ, for the process of the water. Question 2 Water, initially saturated vapor at 10.2 bar, fills...
