This simulation shows a pressure-enthalpy (P-H) diagram for water. Check and uncheck the boxes to add or remove a property from the diagram. You can show lines of constant vapor quality q (blue), temperature T (red), density ρ (gold) and entropy S (purple). You can show grid lines using a checkbox. Check the "critical" box to view the saturated liquid (light blue), saturated vapor (pink) curves and the critical isotherm (blue). View the diagram in color or black and white using buttons.

This simulation was created in the Department of Chemical and Biological Engineering, at University of Colorado Boulder for LearnChemE.com by Neil Hendren under the direction of Professor John L. Falconer. Address any questions or comments to learncheme@gmail.com. All of our simulations are open source, and are available on our LearnChemE Github repository.
