Enthalpy–entropy chart

Template talk:WikiProject Video games Sources for the article. a) Book on Applied thermodynamics by Eastop and McConkey The h-s chart is also known as enthalpy-entropy chart or mollier diagram. In general the chart covers a pressure range of 0.01 - 1000 bar, and temperatures up to 800 degree centigrade. Lines of constant dryness fraction are drawn in the wet region and lines of constant temperature are drawn in the superheated region. In general the chart does not show the values of specific volumes, nor do they show the enthalpies of saturated water at pressures which are of the order of those experienced in condensers in a steam plant. Hence the chart is only useful for enthalpy change in the expansion process of the steam cycles.
