The Mollier diagram coordinates are enthalpy $h$ and humidity ratio $x$. Thus, coordinates on the diagram represent entropy and heat. On the diagram, lines of constant pressure, constant temperature and volume are plotted, so in a two-phase region, the lines of constant pressure and temperature coincide. Source: Wikipedia - Enthalpy–entropy chart These quantum e ects largely vanish at the higher temperatures at which gas production and processing take place. For helium, the critical point is at such a low temperature (T c is approximately 5.2 K) that it is signi cantly altered by quantum e ects.

Are there any relations which cover a higher temperature range, up to 300-400° C? If not, is it not possible to determine saturation point above the boiling point of water?Īt very high temperatures I could only find the Mollier enthalpy-entropy chart (for steam) here's one for up to 1931.67 degrees rankine (800 degrees celsius) and another for up to 2200 degrees rankine (949.072 degrees celsius):
However for most of them the temperature range is not more than 100 C.

How to calculate dew point of air-water system? I want to calculate the maximum water holding capacity of air.
