: A "Lite" version of the app is available on the Apple App Store for field calculations.
In an era of computational fluid dynamics (CFD) and advanced BIM, you might wonder if a spreadsheet-like database is still relevant. The answer is a definitive yes. CFD requires significant time and expertise; the DFDB offers immediate, validated results grounded in decades of laboratory testing.
Larger allowable ranges for dimensions like width (W), height (H), and length (L) to accommodate larger industrial ductwork. Real-Time Calculations: ashrae duct fitting database version. 6.00.05
, ensuring your pressure loss calculations remain accurate and compliant with current ASHRAE standards. What’s New in Version 6.00.05?
: By entering dimensions, airflow rates (CFM/Lps), and fitting types, the software computes the velocity, velocity pressure, and loss coefficient ( Cocap C sub o : A "Lite" version of the app is
The database retains its .DFD file format, but Version 6.00.05 introduces a plugin pathway for Revit and AutoCAD MEP via a COM interface. This allows dynamic lookup of C-values directly from a 3D model—a major time-saver for large projects.
Enter the required dimensional parameters, such as the throat radius ratio ( ) or aspect ratio ( ). Input the flow ratio ( ) if calculating a branch fitting. Step 4: Extract the Results CFD requires significant time and expertise; the DFDB
Design engineers use the database to determine the External Static Pressure (ESP) of a duct system.
