WebSep 9, 2014 · Actual dryness fraction of steam sample, x: x = xa * xb = 0.949 * 0.922 = 0.875. Discussion The dryness fraction of steam describes how dry steam is, with a value of 1 representing steam that is 100% dry, and therefore free of entrained moisture. Steam with a dryness fraction of 0.99 consists of 99% steam and 1% water. Web1) Dryness fraction is defined as the ratio of the mass of actual dry steam to the mass of steam containing it. 2) Critical point a point on a phase diagram at which two phases of a substance have the same density, and are therefore indistinguishable. 3) Triple Point is the temperature and pressure at which solid, liquid, and vapor phases of a ...
