Installation instructions

Installation is very simple, just put the 2 .dll files in the UserEFI
folder in the mathcad program folder
(ex. C:\Program Files\MathSoft\Mathcad 2001i Professional\UserEFI).
Mathcad automatically looks for plugins and loads them on startup.

I have tested this on Mathcad 2001i and Mathcad 14, so it should
probably work in any other version of mathcad, too.

This mathcad plugin makes use of XSteam, a Freeware Steam and water
properties library on the "International Association for Properties
of Water and Steam Industrial Formulation 1997 (IAPWS IF-97).
A full implementation of the IF-97 standard that provides very accurate
steam and water properties in ranges from 0-1000 bar and 0-2000°C for
use in process Engineering Industry.

Provided thermodynamic properties are:
- Temperature
- Pressure
- Enthalpy
- Specific volume
- Density
- Specific entropy

- Specific internal energy
- Specific isobaric heat capacity
- Specific isochoric heat capacity
- Speed of sound
- Viscosity
- Vapour fraction

All properties can be calculated with the inputs, p and T known,
p and h known, h and s known and some with pressure and density known.

An examples.mcd file is provided with the functions available
(or look on http://www.x-eng.com/XSteam_Information.htm for a extended
list of functions available from the xsteam library, although I haven't
implemented all of them, just the ones I required (I'm lazy, I know).

Just email me if you need any other functions from the xsteam library
I haven't implemented. Or just implement them yourself, the source code
is provided (written in Visual C++ 2005, I don't know if it will work
with any other compiler). I'll probably implement the rest of the
functions in future releases.
