We all know the quantity flow charge and tension fall so we can now work out the values for area C and then the remaining ducts.
Jet diffusers even have standardized measurements from 100mm around 600mm or another measurements on ask for dependant upon the maker.
Therefore if we fall Individuals values in for room 1 we obtain a volume move amount of 0.2158m3/s which is the amount air must enter the room to fulfill the cooling load. So just repeat that calculation for all the rooms.
