Inside a piston-cylinder device there is 5 kg of a moist water vapor at 125 kPa. At the beginning there are 2 kg of water in the liquid phase, and the rest is in the vapor phase. Then, heat is transferred to the water; the plunger, which rests on a set of stops, begins to rise when the pressure inside reaches 300 kPa. The Heat transfer continues until the total volume increases by 20 percent. Determine: a) the initial and final temperatures, b) the mass of the liquid water when the plunger starts to rise and c) the work carried out during this process. Also plot the process on a P-v diagram.

Question
Inside a piston-cylinder device there is 5 kg of a moist water vapor at 125 kPa. At the beginning there are 2 kg of water in the liquid phase, and the rest is in the vapor phase. Then, heat is transferred to the water; the plunger, which rests on a set of stops, begins to rise when the pressure inside reaches 300 kPa. The
Heat transfer continues until the total volume increases by 20 percent.
Determine:
a) the initial and final temperatures,
b) the mass of the liquid water when the plunger starts to rise and
c) the work carried out during this process. Also plot the process on a P-v diagram.
