What is Mollier chart in thermodynamics?

An enthalpy–entropy chart, also known as the H–S chart or Mollier diagram, plots the total heat against entropy, describing the enthalpy of a thermodynamic system. A typical chart covers a pressure range of 0.01–1000 bar, and temperatures up to 800 degrees Celsius.

What is Mollier chart used for?

The Mollier diagram is a tool used by engineers to predict, theoretically, the performance of systems and installations. The Mollier diagram, also called the enthalpy (h) – entropy (s) chart or h-s chart, is a graphical representation of thermodynamic properties of materials.

What is significance of Mollier chart?

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.

What do you mean by Mollier chart?

Definition of Mollier diagram : a diagram showing thermodynamic properties of a substance with various quantities (as temperature and pressure) constant especially in terms of entropy and enthalpy as coordinates.

What is the use of Mollier chart?

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.

What is a Mollier diagram in chemistry?

The term “Mollier diagram” (named after Richard Mollier, 1863-1935) refers to any diagram that features Enthalpy on one of the coordinates. Commonly used Mollier diagrams are the enthalpy-entropy (or h-s) diagram ( below) and the pressure-enthalpy diagram illustrated at the bottom of this page.

What does the Mollier chart cover?

Typically, the Mollier chart covers pressure in the range of 0.01 to 1000 bar and up to 800 oC temperature. Mollier diagrams can be plotted for different fluids. The following is the Mollier diagram for water and steam.

What does an enthalpy chart tell you?

An enthalpy–entropy chart, also known as the H–S chart or Mollier diagram, plots the total heat against entropy, describing the enthalpy of a thermodynamic system. A typical chart covers a pressure range of 0.01–1000 bar, and temperatures up to 800 degrees Celsius.

What is the difference between Mollier and psychrometric charts?

Note: The Mollier diagram is a variation of the psychrometric chart, which also plots the thermodynamic properties of moist air. Although they appear vastly different at first glance, rotating the chart by ninety degrees and looking at the mirror image shows the close resemblance between the two charts.
