About CO2 Tables Excel Add-In
The CO2 Tables Excel Add-In library calculates 27 thermodynamic and transport properties
of carbon dioxide. It allows 11 different combinations of input variables to
be used for calculations.
Input variables that can be used are:
- pressure,
- temperature,
- enthalpy,
- entropy,
- volume,
- internal energy,
- and quality (vapor mass fraction).
The library is fully integrated in Excel, and available functions can be used in the same way as any other Excel function.
Main features of the library:
- Professional quality, industrial strength software;
- Based on the formulation for advanced technical applications;
- Accurate and thoroughly tested;
- Create User Defined Functions (UDF) which use CO2Tables functions;
- Developed in C++ for maximum speed;
- Easy to install and easy to use;
- For installation and use of the library no administrator rights required;
- After installation no computer restart required;
- One year free technical support.

CO2 Tables Excel Add-In - Sample calculations in Excel
For thermodynamic properties the library uses new industrial formulation for carbon dioxide,
formulated in Helmholtz energy. It is intended to be used for advanced technical applications.
Equation of state was presented in "Equations of State for Technical Applications" by R. Span and W. Wagner,
International Journal of Thermophysics, Vol.24, No.1, January 2003.
For transport properties the library uses
equations presented in: "The Viscosity of Carbon Dioxide" by A. Fenghour,
W. A. Wakeham and V. Vesovic; "The Transport Properties of Carbon Dioxide" by V. Vesovic, W.
A. Wakeham, G. A. Olchowy, J. V. Sengers, J. T. R. Watson and J. Millat.
System Requirements
Operating system Windows 2000/XP/Vista/Windows 7.
Excel 97 or better.
User privilages
Installation and use of the library requires standard user privilages or better.
