First, for Turkish please visit this topic in samkon forums.
In a specific temperature vapor (water) has a vapor pressure and a boiling temperature those are a function of each one.
Today, I’ve done a programming homework about this calculation.
The equalization that I talk about is below which I found on wikipedia:

Here;
TB = the normal boiling point, K
R = the ideal gas constant, 8.314 J · K-1 · mol-1
P0 = is the vapor pressure at a given temperature, kPa
101.325 = atmospheric pressure, kPa
ΔHvap = the heat of vaporization of the liquid, J/mol
T0 = the given temperature, K
ln = the natural logarithm to the base e
Heat of vaporization (J mol-1) Water = 40650 J/mol
I worked on this formula and make the page below which you can make equalization easily for a specific temperature and TB or Po:

your comments are wellcome to my first English post on samkon.org.. :)
