There are some other sorts of offer air diffusers for sure apps which I have not mentioned below for instance perforated diffusers or displacement air diffusers and linear bar grilles as supply air diffusers.
Even so, it is possible to multiply the air velocity with the duct location to obtain the air quantity. But, It's not the proper way of doing the air balancing work.
Alternatively, swirl diffusers are the combination of both equally the directional and linear slot diffusers. They toss air horizontally and vertically, and the amount of airflow in Every single direction could be adjusted by location their blades.

You may unquestionably get down the measurements you, but leaving that task into the experts is not really a nasty idea. They have got much more experience working with oddly shaped rooms they usually’ll have the capacity to think of far more exact measurements.
