Compressed Air Pipe Line Capacity
Applied Pressure - psi
The diagram below can be used to estimate the flow capacity in a compressed air pipeline with pressure ranging 5 - 250 psi.
- schedule 40 pipe
- for pipes ranging size 1/8" to 1/2" - pressure drop 10% of applied pressure per 100 feet of pipe
- for pipes ranging size 3/4" to 3" - pressure drop 5% of applied pressure per 100 feet of pipe

Applied Pressure - bar
The diagram below can be used to estimate the flow capacity (normal standard air) in a compressed air pipeline with pressure ranging 0.5 - 17 bar.
Example - Capacity in Compressed Air Pipe Line
From the diagram above the capacity of a 1" pipe line at pressure 7 bar is approximately 60-70 liter/s.
