Dry steam, or saturated steam, is characterized by the vapor quality, which is equal to unity. Properties of dry steam are tabulated in so called steam tables. Vapor Quality – Dryness Fraction As can be seen from the phase diagram of water, in the two-phase regions (e.g. on the border of vapor/liquid phases), specifying temperature alone will set the pressure and specifying pressure will set
