Q8) Consider the piston/cylinder arrangement shown. A frictionless piston is free to move between two sets of stops. When the piston rests on the lower stops, the enclosed volume is 400 L. When the piston reaches the upper stops, the volume is 600 L. The cylinder initially contains water at 100 kPa, 20% quality. It is heated until the water eventually exists as saturated vapor. The mass of the piston requires 300 kPa pressure to move it against the outside ambient pressure. Determine the final pressure in the cylinder, the heat transfer and the work for the overall process.

![Q8) Consider the piston/cylinder arrangement shown. A frictionless piston is free to
move between two sets of stops. When the piston rests on the lower stops, the
enclosed volume is 400 L. When the piston reaches the upper stops, the volume is 600
L. The cylinder initially contains water at 100 kPa, 20% quality. It is heated until the
water eventually exists as saturated vapor. The mass of the piston requires 300 kPa
pressure to move it against the outside ambient pressure. Determine the final pressure
in the cylinder, the heat transfer and the work for the overall process.
