Which properties does the Mollier chart plot?
The Mollier diagram, also called the enthalpy (h) – entropy (s) chart or h-s chart, is a graphical representation of thermodynamic properties of materials. In general, it is a relationship between enthalpy (measure of the energy of a thermodynamic system), air temperature, and moisture content.
What is Mollier diagram of steam?
Mollier Diagram: It is a graphical representation of steam tables, in which specific entropy is plotted along the ordinate and specific enthalpy along the abscissa. The diagram is divided into two portions by a somewhat horizontal line termed as saturation curve.
What is the significance of Mollier diagram?
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. The Mollier diagram is a variant of the psychrometric chart.
What is the purpose of Mollier diagram?
The purpose of the Mollier diagram The diagram provides a graphic representation of the relationship between physical conditions and the corresponding changes in the system: the two can be linked simply by drawing some lines and knowing what their intersections represent.
How does a Mollier diagram work?
Which lines have on Mollier diagram?
A typical H-S Mollier diagram for a thermodynamic fluid such as steam is shown in Figure 1. Figure 1. The advantages of such a diagram are that vertical lines represent reversible processes and horizontal lines represent lines of constant energy.
What does the Mollier diagram show?
Air is a mixture of mostly oxygen, nitrogen and water vapor. 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 Mollier chart and its uses?
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. Sponsored Links. Air is a mixture of mostly oxygen, nitrogen and water vapor.
What is HS in thermodynamics?
Enthalpy Entropy (h-s) or Mollier Diagram – Thermodynamics The Mollier diagram, shown in Figure A-1 , is a chart on which enthalpy (h) versus entropy (s) is plotted. It is sometimes known as the h-s diagram and has an entirely different shape from the T-s diagrams.
What is Mollier chart in thermodynamics?
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 a Ph diagram?
A p-h diagram is a figure with a vertical axis of absolute pressure and a horizontal axis of specific enthalpy. It is an important diagram used frequently for a performance calculation of a refrigerating machine. A p-h diagram is made respectively for a specified refrigerant.
What is mean by PV and T-s diagram?
Pressure-volume (P-V) and temperature-entropy (T-S) diagrams are often used as teaching. aids to describe refrigeration processes in introductory textbooks. They trace the path of a. hypothetical element of gas as it moves through a system during a complete thermodynamic. cycle.
What is entropy measured in?
J/K.
The units of entropy are J/K. The temperature in this equation must be measured on the absolute, or Kelvin temperature scale. On this scale, zero is the theoretically lowest possible temperature that any substance can reach.
What is TS and pH diagram?
The P-H and T-S diagram for the simple vapor compression refrigeration cycle is shown in the figure for vapour entering the compressor is in dry saturation condition The dry and saturated vapour entering the compressor at point 1 that vapour compresses isentropic ally from point 1 to 2 which increases the pressure from …
Why do we use p-V diagram?
A pressure–volume diagram (or PV diagram, or volume–pressure loop) is used to describe corresponding changes in volume and pressure in a system. They are commonly used in thermodynamics, cardiovascular physiology, and respiratory physiology.
What is entropy and its unit?
Entropy is a measure of randomness or disorder of the system. The greater the randomness, the higher the entropy. It is state function and extensive property. Its unit is JK−1mol−1.
