Ammonia Properties Calculator

Calculate Thermodynamic and Transport Properties of Ammonia





  Thermodynamic and Transport Properties of Ammonia

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

The NH3 Calculator Web application calculates 30 thermodynamic and transport properties of ammonia. 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 "NH3 Tables Calculator" is based on new industrial formulation for ammonia, 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 Ammonia" by A. Fenghour, W. A. Wakeham, V. Vesovic, J.T.R.Watson, J. Millat, E.Vogel
  • "Equations for Thermal Conductivity of Natural Refrigerants" by J. Yata, M. Hori, Y. Isono, and Y. Ueda
