Make Fluid Property Data Availability as Dynamic as Your Analyses
Select the option that best fits your project needs:
Chempak Property Database
Available individually
Provides the fluid property data, and may be accessed by our pipe system modeling and optimization software, as well as by Chempak Viewer and Chempak Add-in for Excel.
Chempak Plus
Includes:
Chempak Viewer
Chempak Add-in for Excel
Chempak Viewer
Chempak Add-in for Excel
If you already purchased the database, adding the Plus package allows you to use the property database as a stand-alone application. Think of it as an electronic version of your fluid properties reference book (though much more dynamic and capable of determining non-reacting mixture properties)
Chempak Suite
Includes:
Property Database
Chempak Viewer
Chempak Add-in for Excel
Property Database
Chempak Viewer
Chempak Add-in for Excel
Lets you access any fluid property within an Excel spreadsheet. Function inputs may utilize values in any cells, e.g. you could have cells with the fluid type, pressure and temperature and other cells referencing these that calculate the density, state, viscosity, etc.
Chempak Property Database
Comprehensive
thermo-physical properties on a wide range of fluids for AFT's family of pipe flow modeling software products
- For incompressible pipe flow analysis
- - data on ~700 fluids for AFT Fathom, AFT Impulse and AFT Mercury
- - assemble non-reacting static mixtures
- For compressible flow analysis
- - data on ~600 gases for AFT Arrow and AFT Titan
- - model both static mixtures and dynamic mixing resulting from intersecting flow streams
- Fluids listed by up to 3 commonly used names
- Fluids listed by formula and chemical structure
- Sort on any of the identifiers
Chempak Viewer
Access the Chempak Property Database as a stand-alone application
- Assemble non-reacting mixtures on a mass or mole basis
- Calculate fluid or mixture properties for any combination of the available input parameters as a single point, two point or a range of inputs
- Save or set your parameter and unit preferences as the default
- Sand reload input sets
- Save fluid and mixture sets for quick recall using the Recent Fluids list
- Specify a name for any fluid or mixture and it appears along with the standard Chempak name
- Change units 'on the fly' by double-clicking an output column header
Output
- Chempak Viewer provides both text and graphical output
- Configure which parameters are displayed, display order and units
- Supports English and SI units
- Export as a PDF file or to a spreadsheet for additional calculations
- Select a portion of the output and paste into a spreadsheet
- Customize your graphs using colors, axis scale, titles, markers and more
- Use your graphs in other documents
Chempak Add-in
Directly access Chempak fluid property functions from within an Excel spreadsheet
- Imbed comprehensive, accurate fluid properties in your spreadsheet based calculations
- Paste or directly enter Chempak functions as you would with any Excel function
- Fluid selection, assembling mixtures, unit preferences and online help are available from the Chempak menu that appears on Excel’s menu bar
Note:
- Chempak Viewer, Chempak Add-in and Chempak Plus require Chempak Property Database
- Chempak Property Database requires at least one of the following: AFT Arrow, AFT Fathom, AFT Mercury, Chempak Viewer or Chempak Add-in
Chempak FAQ
Aren't the same fluid properties available within AFT software?
No. System modeling software, such as AFT Fathom and AFT Arrow, use and display in their output fluid properties needed for flow analysis, such as temperature, pressure, density, specific heat, etc. In total, about a third of the fluid properties Chempak calculates. All of the fluid properties Chempak calculates are available through the Viewer and the Add-in.
Examples of properties not available within the flow analysis software are; molecular weight, quality, isentropic expansion coefficient and others.
Examples of properties not available within the flow analysis software are; molecular weight, quality, isentropic expansion coefficient and others.
Must commonly used fluids and mixtures always be specified upon opening Chempak Viewer?
What sort of output is available from Chempak Viewer and Chempak Add-in?
Does Chempak have property data for hydrocarbon products?
If I buy a license for the Chempak database, can I use it with other AFT products?
Yes. The Chempak database can be shared and accessed among all AFT products except for the utility suite.
Can I set up my own preferences for output content and engineering units in Chempak Viewer and Excel Add-In?
Can I find out what phase the fluid is in the Viewer and Excel Add-In?
Can I see how a property varies with temperature or some other parameter with the Chempak Viewer and Excel Add-In?
