About O2 Tables Excel Add-In

The O2 Tables Excel Add-In library calculates 29 thermodynamic and transport properties of oxygen.

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
  • 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 O2Tables 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

The following figure shows a sample spreadsheet included in the download package.

Used Formulations

For thermodynamic properties the library uses new industrial formulation for oxygen, 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:

  • "Transport Properties of Fluid Oxygen" by A. Laesecke, R. Kraus, K. Stephan, and W. Wagner, J. Phys. Chem. Ref. Data, Vol. 19, No. 5, 1990
