Description

The site provides a fully functional, professional quality steam tables web application.

The "Steam Tables Calculator" is based on the industrial formulation for calculation of properties of water and steam, called "IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam (IAPWS-IF97)".

For transport properties calculations are based on the latest internationally accepted equations also available from IAPWS.


NEW - Gas Tables

The "Gas Tables Calculator" calculates caloric properties of moist air and undissociated combustion gases from 200 K up to 3300 K. It also provides a dissociation model which enables calculation of caloric properties of dissociated combustion gases at temperatures up to 2000 K, assuming complete combustion with λ > 1.05.

The model is based on the new set of equations for technical applications, called "Thermodynamic Property Models for Moist air and Combustion Gases".

The formulation was developed by D. Bücker, R. Span and W. Wagner, and presented in the "Journal of Engineering for Gas Turbines and Power" (January 2003).
