A handy of free and printable Mollier diagrams have been prepared for you in high definition! The Mollier diagram is a graphic representation of the relationship between air temperature, moisture content and enthalpy, and is a basic design tool for building engineers and designers. In addition, it is
This diagram has a series of constant temperature lines, constant pressure lines, constant quality lines, and constant volume lines. The Mollier diagram is used only when quality is greater than 50% and for superheated steam. For any state, at least two properties should be known to determine the other unknown properties of steam at that state. It is advisable to use Steam-tables or Mollier chart directly for easy and accurate estimation of the properties of steam, such as pressure, temperature, specific volume, enthalpy, entropy etc., which we have calculated by different relations for water/steam in different states under steam generation section.
The constant pressure and constant temperature lines in the Mollier diagram are referred to as isobars and isotherms, respectively. All these diagrams are free to be saved and printed, just click on the image of the diagram to enlarge and save it.
