The value of hf given in the steam tables accounts for the variation in the specific heat of water. Copyright 10. If saturated steam does not contain any water, it is known as Dry Saturated Steam. These tables are to be used because vapours do not obey general gas law. An increase in the pressure or decrease in the temperature will not - within limits - condensate out liquid particles in the vapor. When water is heated to a certain temperature, it starts getting converted to a different phase. The steam may be in any one of the following three conditions: If the temperature of the steam is greater than the boiling point temperature corresponding to the pressure of steam generation, then it is called superheated steam.

In Fig. /FontBBox [-558 -328 2000 1056] As water has liquid form, its gaseous form is called as steam. a) raises immediately The enthalpy added during the superheat phase is the superheat enthalpy. The total heat supplied from OOC is called Enthalpy of Wet Steam (h wet). The values given in the tables are for one kg of dry saturated steam but these values can also be employed for wet steam calculations. Due to the high velocity of steam flow, it remains in the single phase, which is called super-cooled steam.
