How to Use the Database for Pressure Drop Calculation

To illustrate, let’s design a supply duct with a rectangular 90° mitered elbow without vanes (C1-9). Using the ASHRAE Duct Fitting Database 2016, here is the step-by-step process: ASHRAE Duct Fitting Database (DFDB) is a specialized

Comprehensive Library: Includes loss coefficient tables for round, rectangular, and flat oval fittings categorized by supply, exhaust, and common (supply/return) functions.

ASHRAE Duct Fitting Database (DFDB) is a specialized digital tool used by HVAC design engineers to calculate pressure losses in ductwork systems. The 2016 period specifically aligns with Version 6.00.05 and common (supply/return) functions.

The database allows users to select specific duct components and input design parameters—such as airflow (CFM), dimensions, and density—to automatically generate: Loss Coefficients (
