Friction decline is the amount of stress fall that happens inside of a duct because of the resistance in the air movement in opposition to the duct walls, bends, fittings, and obstructions.

The next matter to take into account is the fabric being used for your ducts, and also the roughness of this material as this triggers friction. For instance, if we had two ducts, with equivalent dimensions, volume move amount and velocity, the only real variation is the fabric.
