Minimum Pipe Diameter Required For Headers, Distribution and Drops

Enter the following values:
5
Air Pressure = 100psig
6
Air Flow =96scfm
7
Ambient Pressure =14.7psia
8
9
Calculations:Next standard pipe size (max. 18"):
10
Header (Max. Velocity = 15 ft/sec):
11
Min. Pipe Diameter =1.58in2in
12
13
Distribution (Max. Velocity = 30 ft/sec):
14
Min. Pipe Diameter =1.12in1-1/2in
15
16
Drops (Max. Velocity = 45 ft/sec):
17
Min. Pipe Diameter =0.91in1in
18
19
20
21
Vft/sec =Qscfm
22
CR x 60 sec/min x Asq. ft.
23
24
Therefore header pipe diameter is given by:
25
26
Din =9.6 x Qscfm
27
CR x p x 15ft/sec
