Enter the duct dimensions (Width, Height, or Diameter) and the airflow velocity. Calculate Loss: The software provides the value. You then use the standard pressure loss formula:
The is a critical resource for HVAC engineers, providing the precise loss coefficient data needed to calculate pressure drops in air distribution systems. Version 6.00.05 is one of the more recognized legacy versions of this standalone software, though ASHRAE has since transitioned to cloud-based and updated application formats. ashrae duct fitting database 6.00 05 free download
The DFDB is a paid product developed by ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers). Unauthorized "free" downloads found on third-party sites often contain malware or outdated, corrupted data. Enter the duct dimensions (Width, Height, or Diameter)
