Duct designing with duct sizer software:
Step 1: Select the unit as I.P
Step 2: select 750F air at 50% RH and 1atm
Step 3: Flow rate = 5000 CFM
Friction rate= = 0.08” wg/100’
Step 4: Take your data as required
Duct Sizing A-B
Q=5000CFM f= 0.08” wg/100’
Vmax form table = 2000 FPM
From software
V= 1288.8 FPM < 2000 Then Accepted
Duct A-B = 14’’ x 46’’
Duct Size B-C
Q=4000CFM f= 0.08” wg/100’
B-C = 14’’ x 38’’
Duct Size C-D
Q=3000CFM f= 0.08” wg/100’
C-D = 14” x 30’’
Duct Size D-E
Q=2000CFM f= 0.08” wg/100’
D-E = 14’’ x 22’’
Duct Size E -F
Q=1000CFM f= 0.08” wg/100’
E-F = 14’’ x 14’
(Duct always manufactured with an even scale so 13’’ is taken to 14’’)
Duct Size F-G
Q=500CFM f= 0.08” wg/100’
F-G = 10’’ x 10’’
(When width is less than height in duct sizer, reduce the height so that width will increase to maintain A.R)
