Why spend hours searching for duct fitting pressure drop factors?

This program is a simple browser that will help you to easily find the fitting that you need.

The main feature is that it is used internally by our DuctNet program where it automatically calculates the correct pressure drop.

In the example shown, the fitting selected is the branch of a supply air junction.  The calculated coefficient for the dimensions shown is C = 0.676.  The pressure drop is calculated from the dynamic pressure in the branch.  That is dP = C * ½ ρ V2
