These last equations are useful because they relate equilibrium or saturation vapor pressure and temperature to the latent heat of the phase change, without requiring specific volume data. (en.wikipedia.org)
Do you have the Pressure - Volume - Temperature data, or an equation of state to estimate specific volume at changing salinities? (judithcurry.com)
You're able to adjust on the fly, but I found the volume slider to not be very precise, as I wished it was a dial setting with more «markers» for specific volume levels since it either sounded too low or loud without much room in between to find that perfect setting. (xboxaddict.com)
