Flow Capacity Pipe and Tubes ANSI schedule 40 pipe

The following chart contains the maximum recommended flow rates at the given pressure for ANSI schedule 40 pipe. This chart is applicable for designing compressed air systems.

The flow values in this chart are based on a pressure drop as set forth in the following schedule:

Pressure Drop per 100 Feet of Pipe
Pipe Size - Inches
10% of Applied Pressure
1/8, 1/4, 3/8, 1/2
5% of Applied Pressure
3/4, 1, 1-1/4, 1-1/2, 2, 1-1/2, 3

Nominal Standard Pipe Size - Inch

Derived Units = Pressure Drop per 100 Feet of Pipe (SCFM)
