Steam Tables Calculator

Calculate Thermodynamic and Transport Properties of Water and Steam

Thermodynamic and Transport Properties of Water and Steam

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:

  • Pressure
  • Temperature
  • Enthalpy
  • Entropy
  • Volume
  • Internal energy
  • Steam quality

Used Formulations

Steam Tables

The "Steam Tables Calculator" supports the following formulations for calculation of properties of water and steam:

  • "IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam (IAPWS-IF97)"
  • "IAPWS Formulation 1995 for the Thermodynamic Properties of Ordinary Water Substance for General and Scientific Use (IAPWS-95)"

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

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).
