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.
Select any two properties from the drop down menu, i.e. Pressure and Temperature
Introduce the corresponding properties in the appropriate units: pressure - bar, temperature - K, volume - m3/kg, Enthalpy - kJ/kg, Entropy kJ/kgK
Decimals need to be included with dots and not commas: 3.14 instead of 3,14
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.
Acknowledments
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.

We need a material transition, not only energetic, that restores nature and effectively reuses materials. Gaia must be cared for by extending life on Earth and slowing its degradation towards Thanatia.
Thermodynamics for Sustainable Management of Natural Resources
Wojciech Stanek (Editor)
This book examines ways of assessing the rational management of nonrenewable resources. Integrating numerous methods, it systematically exposes the strengths of exergy analysis in resources management.
Thanatia: The Destiny of the Earth's Mineral Resources
A Thermodynamic Cradle-to-Cradle Assessment by (author): Antonio Valero Capilla and Alicia Valero Delgado
Is Gaia becoming Thanatia, a resource exhausted planet? For how long can our high-tech society be sustained in the light of declining mineral ore grades, heavy dependence on un-recycled critical metals and accelerated material dispersion? These are all root causes of future disruptions that need to be addressed today.
