Function names ending with e mark functions to be used for calculations in English Units.

Function names ending with si mark functions to be used for calculations in SI Units.

Next follow two capital letters denoting the first and the second input parameters of a function, for example PT stands for pressure and temperature respectively.

Functions applicable in all regions, as defined by the IAPWS-IF97, start with Steam.

Functions applicable only in the saturation region, as defined by the IAPWS-IF97, start with Sat.

In order to easily identify functions to be used, function names are formated using the following rules:

NOTE:The Steam97 Excel Add-In libraries cannot be shipped to a third party as a part of your VBA application. IAPWS-IF97 improves significantly both accuracy and speed of the calculation of the thermodynamic properties compared with the old formulation.įor transport properties calculations are based on the latest internationally accepted equations also available from IAPWS. The library uses new industrial formulation for steam tables, called 'IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam (IAPWS-IF97)', and replaces the previous industrial formulation for steam tables, IFC-67.

Call Steam97 functions from VBA (samples are included in the release version).

Extend the library with User Defined Functions ( UDF).

Developed in C++ for maximum speed, thoroughly tested for accuracy.
