Thermodynamics
The following GUI and/or Excel files and MATLAB functions can be used to read data and determine properties from the Thermodynamic Tables.Please do not edit/modify any of these files/functions. They contain copyrighted information. The MATLAB functions are in an encrypted format (*.p extension). These can be used as any other *.m file. The syntax help for these functions are shown in the table below.
The best way to download the files is to use the right-click and save as option.
| Description | Files | Help |
|---|---|---|
| Graphical User Interface (GUI) | Thermodynamic GUI.zip |
Unzip into a folder and execute the file thermoGUI.p in MATLAB. The GUI can be used to determine all properties. |
| Tables | Thermodynamics Tables SI Units.xlsx Thermodynamics Tables English Units.xlsx |
These Excel files have all the properties listed in a format similar to most textbooks |

While these functions have been used for 3-5 semesters in a
Thermodynamics course for Mechanical Engineers, they
have not been tested for all cases. Please let the Project Director Dr. Priya Goeser know
if you find any errors and/or if you wish to use them for any similar courses/educational purposes.
