Wet Steam vs. Dry Steam: The Importance of the

2018-12-3 · Unless a superheater is used, this will cause the steam supply to become partially wet (wet steam) from the added liquid. Steam Dryness Fraction. The steam dryness fraction is used to quantify the amount of water within steam. If steam contains 10% water by mass, it's said to be 90% dry, or have a dryness fraction of 0.9.
