    Enthalpy–entropy chart - Wikipedia

    An enthalpy–entropy 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. [2] A typical chart covers a pressure range of 0.01–1000 bar, and temperatures up to 800 degrees Celsius. [3]

    Thermodynamics Basics: Enthalpy, Entropy, Mollier Diagram …

    Enthalpy: Enthalpy is defined as the total heat content or total useful energy of a substance. The symbol for enthalpy is “h.” Enthalpy is also considered to be the sum of internal energy “u” and flow energy (or flow work) p.V. This definition of enthalpy can be expressed, mathematically, as follows: h = u + p.V Eq. 1.1 Where,

    Enthalpy Entropy (h-s) or Mollier Diagram - Engineers Edge

    Enthalpy Entropy (h-s) or Mollier Diagram. 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.
