Heat of vaporization.
Heat of vaporization.
(OP)
Hello,
I am trying to find a correlation for the heat of vaporization of water versus temperature.
I found this on wikipedia,
htt p://en.wik ipedia.org /wiki/Enth alpy_of_va porization
but the graph on the right has no correlation displayed. The purple line is what im looking for.
The purpose of this is to build an equation that can calculate the boiling point of water given temp and pressure without having to use a thermo lookup table.
Thank you

The data for those curves were obtained from the Dortmund Data Bank ... which is quite expensive to purchase. If you have access to a good university library, they may have a copy available. The URL of the Dortmund Data Bank is:
