The site provides a feature rich, professional quality Steam Tables web application for calculation of thermodynamic and transport properties of water and steam and thermodynamic properties of combustion gases.
The steam tables application calculates 32 thermodynamic and transport properties of water and steam. It allows 16 different combinations of input variables to be used in calculations.
Input variables that can be used are:
The "Steam Tables Calculator" supports the following formulations for calculation of properties of water and steam:
For transport properties calculations are based on the latest internationally accepted equations also available from IAPWS.
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:
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).
The Registration is valid for 5 months (150 days), and it will not be extended automatically. After 5 months if you wish to continue using the premium features of the application you will have to register and create a new account again.
The Registration includes free technical support for the duration of the subscription.
This is a 5 months subscription fee for using the Steam Tables Calculator and the Gas Tables Calculator online.
