ASSUMING DUCTING IS FOR VENTILATION ONLY: (Duct Sizing for the terrified, 2014. EDP: Episode 03. Available from blackboard . Welsh School of Architecture, Cardiff University)
required air = 8 l/s/p
(assuming max occupancy): 6 people
=8*6=48 l/s = 0.048m3/s
Assuming general areas the speed is:
diffusers = 2m/s
branch ducts = 3m/s
main ducts=7m/3
cross section = volume / speed allowed
diffuser:
0.048/2 = 0.024m2 cross section
branch ducts:
0.048/3=0.016m2 cross section
main ducts:
0.048/7=0.007m2 cross section
The same amount of duct work is needed for the exhaust
