SteamTab Duo V3.0
Introduction
SteamTab Duo sets a new standard in capability and ease of use for steam property generation. It contains all the features of SteamTab Version 3.0 and allows you to choose either the scientific formulation or the industrial formulation for steam property calculations.
Choice of formulations
With SteamTab Duo, you can choose from two different
formulations to base steam property calculations:
- Scientific Formulation (IAPWS-95): This is the formulation approved by the International Association of the Properties of Water and Steam (IAPWS) in 1995 for general and scientific use. This formulation is more thermodynamically rigorous, accurate, and applicable over wider range of conditions.
- Industrial Formulation (IAPWS-IF97): This is the IAPWS approved formulation of industrial and special use. The industrial formulation is based on an approximation of the scientific formulation and is generally used in situations where computational speed is of importance.
Using SteamTab Duo in a spreadsheet allows you to examine a large number of design scenarios for optimisation and visualise the results in great looking tables and charts. SteamTab Duo can also be used to generate Mollier charts and steam tables in your own choices of units, graduations, or language.
Package contents
The SteamTab Duo add-in package contains:
- Spreadsheet add-in files containing the SteamTab Duo functions and SteamTab Duo user-interface consisting of dialog boxes and the SteamTab toolbar
