Carbon Dioxide Properties Calculator

Calculate Thermodynamic and Transport Properties of Carbon Dioxide

Thermodynamic and Transport Properties of Carbon Dioxide

The site provides a feature rich, professional quality CO2 Tables web application for calculation of thermodynamic and transport properties of carbon dioxide.

The CO2 Calculator Web application calculates 29 thermodynamic and transport properties of carbon dioxide. It allows 11 different combinations of input variables to be used in calculations.

Input variables that can be used are:

  • Pressure
  • Temperature
  • Enthalpy
  • Entropy
  • Volume
  • Internal energy
  • Quality (vapor mass fraction)

Used Formulations

The "CO2 Tables Calculator" is based on 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
  • "A Reference Multiparameter Thermal Conductivity Equation for Carbon Dioxide with an Optimized Functional Form" by G. Scalabrin, P. Marchi, and F. Finezzo and R. Span.
