ASHRAE Fundamentals Handbook

If you’ve ever spent hours manually calculating pressure drops through elbows, transitions, or tees, you know the pain. We all rely on the (Chapter 34, to be precise) for those loss coefficients. But flipping through pages or scanning PDFs is tedious. ashrae duct fitting database excel link

ASHRAE Duct Fitting Database (DFDB)

The is the industry-standard reference for designing and analyzing ductwork systems. It provides the loss coefficients ($C$-values) required to calculate pressure losses for various duct fittings (elbows, transitions, take-offs, etc.). Harnessing the ASHRAE Duct Fitting Database in Excel
