Within the considerably conclusion of the most crucial duct the air is split into two branches via a gentle, curved tee section. This allows the air to easily improve path get more info and so there is absolutely no sudden boost in static pressure and here also the air flow level to the rooms has drastically amplified.

Now for this we want to take into consideration which the air is transferring in two directions, straight through and in addition turning off into the branch so we need to conduct a calculation for both directions.

In these types of conditions, some linear slot diffusers are dummies and are not connected to any supply or return air duct. Only for aesthetic functions.
