NH3 Tables

The site provides a feature rich, professional quality NH3 Tables web application for calculation of thermodynamic and transport properties of ammonia.

The "NH3 Tables Calculator" is based on the industrial formulation for ammonia, formulated in Helmholtz energy, and presented in "Equations of State for Technical Applications" by R. Span and W. Wagner.

For transport properties the application uses equations presented in: "The Viscosity of Ammonia" by A. Fenghour, W. A. Wakeham, V. Vesovic, J.T.R.Watson, J. Millat, E.Vogel; and "Equations for Thermal Conductivity of Natural Refrigerants" by J. Yata, M. Hori, Y. Isono, and Y. Ueda.
