Wet Steam vs. Dry Steam: The Importance of the Steam

Calculating the Total Heat of Wet Steam. Steam tables contain values such as enthalpy (h), specific volume (ν), entropy (s), etc. for saturated steam (100% dry) and for saturated water (0% dryness), but typically not for wet steam. These can be calculated by simply considering the ratio of steam to water, as described in the equations below:

Enthalpy values are used to represent the energy level of steam entering a turbine, a value useful for determining turbine efficiency. By superheating steam, we can add enthalpy to steam without raising the pressure of the steam. For example, steam at 620 psig and 850°F can do more work in a turbine than steam that is 620 psig and 650°F. 2.
