    This document contains information from the ASHRAE duct fitting database. It provides specifications for a smooth radius elbow fitting with one splitter vane, including inputs like width and radius ratio and outputs like throat radius and pressure loss. It also details a 45 degree tee fitting with a diverging branch, listing inputs like heights, widths, and flow rates, and outputs like velocities, velocity pressures, and loss coefficients for both the branch and main sections.
