Mollier diagram vs psychrometric chart. The y-axis represents the temperature nd the x-axis absolute humidity. The Mollier diagram is a thermodynamic diagram that represents the enthalpy of a system which can be a mixture or a chemical substance as a function of other thermodynamic quantities. In this scenario I require what amount of maximum moisture can Cl2 or H2 hold up at specific temperature pressure precisely 85celsius 12bar absolute.

The Mollier Chart also called enthalpy entropie chart the h-s chart or called the psychrometric chart is a chart devised by Richard Mollier in 1904 that expands the enthalpy against entropy. At the Thermodynamics Conference in Los Angeles 1923 it was decided to name the diagram after Richard Mollier in his honor. Air is a mixture of mostly oxygen nitrogen and water vapor.

M³sec m³h kgsec 0-50 Ref. The Mollier Diagram is the European version of the Anglo-American Psychrometric Chart.

At first inspection there may appear little resemblance between the charts but if the user rotates a chart ninety degrees and looks at it in a mirror the resemblance is apparent. Chlorine Hydrogen Psychrometric or Mollier Chart. Altitude above sea level m.

The more I teach this subject the more parallels I see between it and refrigeration theory which also involves vaporization and condensation and has its own chart known as a Mollier diagram which Ive also heard psychrometric charts referred to as. Such diagrams find use in design include steam turbines refrigeration weather forecasting and air drying systems for the food sucks as coldstores and freezer room calculations. In our electrolysis of brine Cl2 H2 are produced as gaseous products along with aqueous NaOH.

At the Thermodynamics Conference in Los Angeles 1923 it was decided to name the diagram to Richard Mollier in his honor. Two coolers shelltube exchanger with. The conditions of drying air throughout the drying process are illustrated by the psychrometric chart Mollier diagram or h-x sometimes i-x diagram.

Use the psychrometric chart to determine the specific humidity ω 18 gm-moisturekg-air the enthalpy h 78 kJkg-air the wet-bulb temperature Twb 255C the dew-point temperature Tdp 23C and the specific volume of the dry air v 089m3kg. I dont know if youve ever heard of the Refrigeration Service. While connecting the dots Mollier ended up with the famous H-S diagram which plots total heat against entropy.

The Mollier i-x Enthalpy - Humidity Mixing Ratio diagram developed by Richard Mollier in 1923 is an alternative psychrometric chart preferred by many users in Scandinavia Eastern Europe and Russia. The Mollier diagram is a variant of the psychrometric chart. Psychrometry from the Greek.

The Psychrometric Chart is also known as the Mollier-Diagram when the axes are flipped. This shows the state and every property which belongs to it in a fairly simple chart. Concepts used in psychrometry.

The diagram is shared under creative common licence from Wikipedia author ArthurOgawa. Psychrometric diagrams of Carrier and Mollier for psychrometric calculations of humid air for educational use only. A Mollier diagram express the same psychrometric properties as a psychrometric chart.

Note that the Mollier diagram is actually identical to the psychrometric chart but just mirrored and turned 90 degrees. I will describe first the Mollier diagram and then show the simple transformation that changes it into the psychrometric chart. The Mollier diagram also called the ix diagram is based on the relationship between heat content.

The Mollier diagram is a graphic. The psychrometric chart is constructed so that the isotherm corresponding to 0C is horizontal. The process of transforming a Mollier diagram to a psychrometric chart - or vice versa - is shown below.

The Mollier diagram coordinates are enthalpy h and humidity ratio x. The process transforming a Mollier diagram to a psychrometric chart is shown below. Mollier Psychrometric analysis and charting software.

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. First it has to be reflected in a vertical mirror then rotated 90 degrees. Indicate all the values determined on the chart.

ψυχρόν cold and μέτρον measurement means the study inherent in the determination of the properties of a gas-vapor system. Psychrometric Chart The psychrometric chart is a variant of the Mollier diagram used in some parts of the world. I will describe first the Mollier diagram and then show the simple transformation that changes it into the psychrometric chart.

They are identical in content but not in appearance. 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. The chart is is combined with the Relative Humidity lines and the Enthalpy to calculate the change in total internal energy.
