Ashrae Duct Fitting Database 2016

Users enter data such as flow rate (CFM or L/s), duct dimensions (height, width, or diameter), and fitting geometry (radius ratio, angle).

The 2016 edition of the DFDB built upon previous iterations (notably the 2009 and 2012 versions) to offer enhanced usability and expanded data. Key features included: ashrae duct fitting database 2016
