Question:

In an evacuated vessel with a volume of 280 liters, 1.0kg of water is injected. At equilibrium, the pressure of the vessel is 80psi. Determine the mass (kg) and density (kg/liter) of water vapor in the vessel and the mass and density of liquid water in the vessel.

Quality.

It is the ratio of the mass of the steam divided by the total mass. It is a thermodynamic property defined in the region of saturated mixture of phases. In the saturated liquid state the quality is zero, while in the saturated steam state, the quality is 1 (or 100 percent).
