Pair v60005 with the SMACNA HVAC Duct Construction Standards for a complete workflow—losses + gauge + sealing.
However, static tables have limitations. They offer interpolation, but rarely extrapolation, and they struggle to dynamically account for varying Reynolds numbers or entrance conditions. The ASHRAE Duct Fitting Database was created to solve this. Version 6.0.005 represents the latest maturity of this tool, fully integrated with modern calculation engines. It does not merely replicate the handbook; it creates a dynamic environment where the physics of airflow are calculated in real-time. ashrae duct fitting database version 60005
Featuring pictorial outlines of each fitting, this database is useful to design engineers dealing with a variety of duct fittings. ashrae.org Duct Fitting Database Lite App - ASHRAE Pair v60005 with the SMACNA HVAC Duct Construction
