AFT SteamCalc calculates properties using the 1997 ASME Steam Tables formulation, the most respected source available. An alternate formulation from NBS is also provided. Now engineers can conveniently access reliable steam and water properties on their desktop PC.

AFT SteamCalc Viewer

AFT SteamCalc Viewer provides three ways to calculate steam and water properties from a wide range of available input parameters using either ASME 1997 or NBS:

- Single point - a pair of input parameters with output displaying selected parameters for the single point
- Two points - two pairs of input parameters with output displaying parameters for both points and the difference in value between the two points for each parameter
- Range - one parameter a single value with the second specified by a start value, end value and increment, with output displaying properties for each increment over the range

Output is user configurable for parameters displayed, display order and number of digits. English and SI input and output units are supported. These parameter and unit preferences may be saved, reloaded and set as the default. Input sets may be saved and reloaded. Results can be printed, copied to the Windows clipboard, saved to a formatted file, saved to a delimited file, and saved to an Adobe PDF file.

Any of the available output properties may graphed over an input range with the graph customizeable for colors, axis scale, titles, markers and more. Graphs may be printed copied or saved as jpg files for insertion into other documents.

AFT SteamCalc Add-in for Excel

AFT SteamCalc Add-in lets you directly access ASME and NBS steam/water property functions from within a Microsoft Excel spreadsheet. Your spreadsheet based calculations can now have comprehensive and highly accurate fluid properties imbedded as a dynamic part of your analysis. SteamCalc functions may be pasted or directly entered as you would with any Excel function. Unit preferences and online help are all available from the SteamCalc menu that appears on Excel’s menu bar.
