The rigid tank illustrated in the Figure has a volume of 0.06 m3 and initially contains a two-phase liquid–vapor mixture of H2O at a pressure of 15 bar and a quality of 20%. As the tank contents are heated, a pressure-regulating valve keeps the pressure constant in
the tank by allowing saturated vapor to escape.
(a) determine the total initial and final masses in the
tank, in kg, and the amount of heat transfer, in kJ, if
heating continues until the final quality is x = 0.5.
(Ans. 2546.5 kJ)
(b) plot the total mass in the tank, in kg, and the amount of heat transfer, in kJ, versus the final quality x ranging from 0.2 to 1.0.
I know how to solve part (a) but I don't know how to plot (part b) , help me please.
