SUMMARY
The recommended maximum CFM for compressed air at 90 PSI through various pipe sizes is as follows: 1/2" pipe can handle 74 SCFM, 1" pipe 295 SCFM, 1.25" pipe 608 SCFM, 1.5" pipe 912 SCFM, and 3" pipe 4946 SCFM. These values assume a clean, schedule 40, steel pipe and a pressure drop of 2 PSI per 10 feet of pipe. The actual flow rate can vary significantly based on system specifics, including pipe length, fittings, and material type. For precise calculations, users are encouraged to utilize online pressure drop calculators.
