A Mollier diagram or steam tables allow determination of the energy available in a pound of steam for a specific pressure and temperature. Thermodynamics is the branch of physical science that deals with the relations between heat and other forms of energy such as mechanical electrical or chemical energy and by extension of the relationships between all forms of energy. You will get introduced to Mollier diagram and learn how to utilize it in the assessment of enthalpy and entropy changes as temperature and pressure are changed.

Richard Mollier was a professor of Applied Physics and Mechanics and a pioneer of experimental research in thermodynamics in the late 19th century. The enthalpy- entropy charts in Appendix B are Mollier Diagrams. Steam tables or a Mollier diagram.

The Mollier diagram is the representation of the properties of water and water vapor. The diagram was created in 1904 when Richard Mollier plotted total heat against entropy. The Mollier diagram is useful when analyzing the performance of adiabatic steady-flow processes such as flow in nozzles diffusers turbines and compressors.

Mollier diagram is chart drawn between enthalpy H on ordinate and entropy or S on abscissa. 119 STATE the First Law of Thermodynamics. The dryness fraction x gives the fraction by mass of gaseous water in the wet region the remainder being droplets of liquid.

Mollier diagram is a graphical representation of a functional relationship between enthalpy entropy temperature pressure and quality of steam. An enthalpyentropy chart also known as the H S chart or Mollier diagram plots the total heat against entropy 1 describing the enthalpy of a thermodynamic system. It is also known as the h-s diagram.

A typical H-S Mollier diagram for a thermodynamic fluid such as steam is shown in Figure 1. The accompanying CD includes a fully func-tional student version of QuickField software tutorials etc. The Mollier diagram is used only when quality is greater than 50 and for superheated.

The Mollier diagram also called the enthalpy h entropy s chart or h-s chart is a graphical representation of thermodynamic properties of materials. Please feel free to download. Mollier diagram Pro is available through the following options.

Richard Mollier 1863-1935 was a professor at Dresden University who pioneered the graphical display of the relationship of temperature pressure enthalpy entropy and volume of steam and moist air that has since aided the teaching of thermodynamics to many generations of engineers. Mollier Diagram Pro is an easy to use mollier diagram with which you can make calculations of air treatment processes. Molliers H-S diagram Enthalpy v Entropy was a logical extension of the T-S diagram Temperature v Entropy first proposed by Gibbs retaining the advantages of T-S diagrams but introducing several new advantages.
