Steam Table, A complete IAPWS IF-97 standard

[Powersoft]

Hi all,

Please find my implementation of the Steam Table for the HP-Prime

It is based on the version of :
X Steam, Thermodynamic properties of water and steam.
by Magnus Holmgren

30 Jan 2006 (Updated 01 Aug 2007)
Water properties A complete IAPWS IF-97 standard.

It is still in progress! Next step is to make a nice App.
All functions are implemented, except he transport functions!

Small help:
Water and steam properties according to IAPWS IF-97.

This Steam Table provides accurate steam and water properties from 0 - 1000 bar and from 0 - 2000 deg C according to the standard IAPWS IF-97.
For accuracy of the functions in different regions see IF-97 (http://www.iapws.org)
