1/4” Schedule 40 Pipe | Actual ID = .365
The table below shows the airflow pressure drop in Pounds per Square Inch per 100 feet of schedule 40 pipe.
FOR EXAMPLE, if Jory has a line pressure of 100 PSIG with an airflow of 15 SCFM moving through the 100 feet of pipe, he would experience a drop in pressure of approximately 13 Pounds per Square Inch.
