just like.......!!
10'x10' 2 room, 12'x10' 1 room, Kitchen 10'x 8' and this
rooms and Kitchen Height is "10 fit" total area is 4000
Square fit.
(air speed) 600FPM (main line air supply speed) 750 FPM
bar room =
10 height x 10 Length x 10 width = 1000Sq fit
Air-Conditioning air supply is 1000CFM
10'X 10' room 250 CFM each
12'x 10' room 300 CFM
Kitchen 10'x 8' 200 CFM
Main line suppy air is 750 FPM
1000/750 X 144 = 192

1) Cfm of duct
2) Required static pressure in duct
3) Shape of duct piece like bent, offcet, length, round etc
4) If any heating or cooling element to be install in duct.
