Jet diffusers also have standardized dimensions from 100mm up to 600mm or every other measurements upon ask for with regards to the manufacturer.
So if we fall those values in for place 1 we have a volume circulation level of 0.2158m3/s that may be exactly how much air should enter the space to fulfill the cooling load. So just repeat that calculation for many of the rooms.
