"The math doesn't add up, Elias," his boss had barked. "If we're off by even half an inch of water gauge, the fans will stall, and the archives will rot." The ASHRAE Duct Fitting Database version 60005 can

The ASHRAE Duct Fitting Database (DFDB) is the industry-standard reference for loss coefficients for HVAC duct fittings. It is the digital embodiment of the data found in the ASHRAE Handbook of Fundamentals and ASHRAE Research Project 1053-RP. Engineers and HVAC designers use it to calculate pressure losses in duct systems accurately, enabling energy-efficient building design.

does not publicly release its Duct Fitting Database for free. The database is a proprietary, commercially licensed product used with design software (like Wrightsoft, Elite, or Trane Duct Designer). Version numbers like "60005" do not correspond to any official ASHRAE release I can verify; official versions are typically tied to ASHRAE Fundamentals Handbook updates (e.g., 2005, 2009, 2013, 2017, 2021). It contains loss coefficients ($C$) for virtually every
