Functions for properties of steam/water

Functions for properties of steam/water are based on IFC formulation for industrial use. When you activate STMXL.XLA, you have access to all steam/water functions. By pressing fx button in MS Excel a dialog over all function comes up. Select "User Defined" and you will have a list over all user defined functions. When you pick a function, a brief description of the function appears at the bottom of the dialog box. If you press "Next", Excel will continue with a dialog box that asks for the necessary inputs for the function. In case, you press "Enter" button, you should fill all the parameters with numbers, cell reference, variable name and so on. These are the normal Excel functions behavior and is not specific for this program. If you need more help please see the on-line help of MS Excel or the user manual. The function names are compatible with the DLL version of steam properties. Those users who upgrade to this version from DLL version of steam properties will find several new functions. There are some simple rules that will help you to remind function names. Here, you have a complete list of functions for properties of steam and water. A print of this page will be helpful if you are new to this package.
