A piston-cylinder device contains a saturated mixture of steamand water having a total mass of 0.5 kg at a pressure of 160 kPaand an initial volume of 100 liters. Heat is then added and thefluid expands at constant pressure until it reaches a saturatedvapor state.
a) Draw a diagram representing the process showing the initialand final states of the system.
b) Sketch this process on a P-v diagram with respect to thesaturation lines, critical point, and relevant constant temperaturelines, clearly indicating the initial and final states.
c) Determine the initial quality and temperature of the fluidmixture prior to heating. [quality x1 = 0.182, T1 = 113.3°C]
d) Determine the final volume of the steam after heating. [0.546m3 (546 liters)]
