1) 2-49 A rigid tank with a volume of 2.5 m3 contains 5kg saturated liquid-vapor mixture of water at 75 °C is heated slowly. The temperature at which the liquid in the tank is completely vaporized is to be determined, and the T-v diagram is to be drawn (you don't have to do this in the online submission).
2) 2-52 A 0.5 m3 rigid vessel contains 10 kg of R-134a at -20 °C. The pressure, total internal energy, and the volume of the liquid phase are to be determined.
