Pressure-Enthalpy Diagram for Water
This Demonstration shows a pressure-enthalpy () 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 (blue), temperature (green), density (orange, dashed) and entropy (purple, dashed). You can show grid lines using a checkbox. Check the "critical" box to view the saturated liquid (light blue), saturated vapor (red) curves and the critical isotherm (magenta). View the diagram in color or black and white using buttons.
