Whether or not your system flows within the minimal or the most of the array is depending on the system’s friction decline along with the tools decided on. Friction reduction is the quantity of stress drop that happens in the duct as a result of resistance from the air move towards the duct walls, bends, fittings, and obstructions.
The second issue to consider is the fabric being used for the ducts, plus the roughness of this substance as this leads to friction. As an example, if we experienced two ducts, with equivalent dimensions, quantity flow rate and velocity, the only real change is the fabric.
