Freesteam is a library that allows you to
calculate water and steam properties using the
industry-standard IAPWS-IF97 steam tables. It is a
library of C++ classes which can be integrated
into your code. Plug-ins to allow freesteam to be
integrated with spreadsheets and other
applications are under development. The included
unit tests assure compliance with published
property values. IAPWS-95 (scientific use)
correlations are also included and used as part of
this validation.
