SteamTab V3.0
Introduction
SteamTab V3.0 uses the highly accurate international standard IAPWS-95 Formulation for General and Scientific Use. This formulation represents the most accurate current embodiment of scientific understanding of water and steam properties.
Product overview
Designers of steam processing systems and equipment use a variety of conventional methods to look up steam properties for engineering calculation, including printed steam tables in different units, stand-alone steam property software, proprietary design software, general-purpose process simulators and long-hand calculations from fundamental equations. Lookup from printed steam tables remains the most frequently used method for daily use of steam properties. The interpolation of property values between fixed state points is a tedious, boring, and prone-to-error exercise that has plagued many generations of engineers.
SteamTab, designed as an add-in package to popular spreadsheet applications, allows users convenient acces to a variety of steam property values without leaving the spreadsheet computation environment. SteamTab contains a comprehensive set of water and steam properties applicable over a wide range of conditions (temperature: 190 to 5,000 K; pressure: 0 to 100,000 bar), with selected derivative and dimensionless properties.
Using SteamTab in a spreadsheet allows you to examine a large number of design scenarios for optimization and visualise the results in great looking tables and charts.
SteamTab could also be used to generate Mollier charts and steam tables in your own choices of units, graduations, or language.
Range
The IAPWS-95 formulation is valid in the entire stable fluid region of water. SteamTab imposes the following temperature and pressure restrictions:
- Pressure (P, bar): 0 <= P <= 100,000
- Temperature (T, K): 190 <= T <= 5,000
Package contents
The SteamTab add-in package contains:
- Spreadsheet add-in files containing the SteamTab functions and SteamTab user-interface consisting of dialog boxes and the SteamTab toolbar
- A dynamic link library (DLL) containing the core steam routines
- On-line, context sensitive help files
- A 40 page manual with a SteamTab function quick reference card
- Free technical support
