Currently, the flow exergy calculator only contains substance water/steam (i.e. liquid and vapour states for water as a real substance). In the future, we will incorporate more substances.
If your entered values are out of range, the programme will tell you so.
The calculator will provide as results the temperature, pressure, specific volume, specific internal energy, specific enthalpy, specific entropy and specific exergy of the substance.
The equations are obtained from Reynolds, William Craig. Thermodynamic properties in SI-graphs, tables and computational equations for 40 substances. University, Departement of mechanical engineering, 1979.
We would like to acknowledge Mr. Tomás Gómez for providing the necessary algorithms to implement the flow exergy calculator in Exergoecology.
A more advanced thermodynamic calculator for many more substances and with a graphical interface is Thermonator.
Here you can download Thermonator for Android.
