What is Specific Volume of Wet Steam – Definition

In case of wet steam, the actual specific volume can be calculated with the vapor quality, x, and the specific volumes of saturated liquid water and dry steam. Thermal Engineering

Specific Volume of Wet Steam

Similarly, the specific volume of saturated liquid water (x=0) and dry steam (x=1) can be picked from steam tables. In case of wet steam, the actual specific volume can be calculated with the vapor quality, x, and the specific volumes of saturated liquid water and dry steam:

vwet = vs x + (1 – x ) vl              

where

vwet = specific volume of wet steam (m3/kg)

vs = specific volume of “dry” steam (m3/kg)

vl = specific volume of saturated liquid water (m3/kg)
