WELCOME  to our History Page!

Its purpose is to bring back, from time to time, historical subjects in a form
that may appeal to larger audiences, either through translation or simplified
reinstatement.

As first subject we have chosen the work of Professor Richard Mollier on the
thermodynamics of {Air + Water vapor} mixtures, in particular the
Mollier hx-Diagram.

This is timely, since Professor Mollier died 70 years ago (March 13, 1935).

To remember and honor him and his work, we have translated to English his
two seminal papers on the subject of psychrometry of the {Air + Water vapor}
mixtures, and provide them for free download here.

R. Mollier 1923 - A new diagram for air + water vapor mixtures

R. Mollier 1929 - The ix-diagram for air + water vapor mixtures.
