@Gas is a member of Techware¡¯s family of
software packages bringing accurate thermodynamic properties of fluids to
many popular Windows programs.
The gas property functions can be used
directly from within applications including Microsoft Excel, 1-2-3 and
MathCad. Add-ins attach the functions so that you can use them as if
they were built in to the applications.
What's New in Version 4.0
- Added 64-bit version of Gas property DLL.
- Added 64-bit version of DeskTop Gas.
- Converted all help files to compiled HTML
format.
- Removed @Gas Help link from all versions of
Excel and 1-2-3 menus.
- Updated on Jan 11, 2022 to add missing
TGas64.lib file for those wishing to program in C++.
Key Features
- Seamlessly extends your spreadsheet program's
set of built-in functions.
- Equations based on virial equation of state
using second and third order mixing coefficients. No perfect gas
assumptions.
- Accuracy fully documented.
- Supports many combinations of input data.
- Uses English, SI and metric unit sets.
- Allows pressures up to 50 bar (725 psia)
and temperatures from 180 ¡ÆK (-135.67 ¡ÆF) to 2000 ¡ÆK (3140 ¡ÆF).
- Calculates specific volume, enthalpy, entropy,
specific heat, viscosity and thermal conductivity.
- Calculates humidity ratio, molecular weight,
amount of condensation and dew point.
- Express moisture as humidity ratio, mole
fraction or mass fraction.
- Express results on wet or dry basis.
Applications Supported
The @Gas package
includes various add-ins which link the functions to many popular 32-bit and
64-bit Windows applications. 32-bit add-ins are included for Microsoft Excel
versions for Office 95, Office 97, Office 2000; Office XP; Office 2007 and
Office 2010 (32-bit version), Lotus 1-2-3 97 and 1-2-3 Millennium (Rel 9.0)
and MathSoft Mathcad Plus Versions 6, 7 and 8. A 64-bit add-in is
included for Office 2010, 2013, 2016 and 365 (64-bit version.)
No programming is required to use
the @Gas functions with any of these applications. Just
follow a few simple steps to load the add-in, and from then on, the functions
will be available every time you start the application. You use the functions
just like any of the built-in functions. The functions can be used in any
spreadsheet formula and any argument to the functions can be a number, a
formula or a cell reference.
