Dryness fraction of wet steam is

WebWhen a substance exists as a part liquid and part vapour at saturated conditions, it is quality or dryness fraction (x) of steam is defined as the ratio of the mass of the dry steam to the total mass of both dry steam and liquid. x = m g m f + m g ( 0 ≤ x ≤ 1) where m g = mass of the dry steam and m f = mass of liquid WebSaturated Steam Table. In many applications, saturated steam may contain both water vapor and water droplets, so it is necessary to specify the "dryness" of the steam in order to determine its thermal properties. The dryness is the mass fraction of the vapor in a steam, so 0% dryness means all liquid with no vapor; while 100% dryness means all ...
