Im trying to find the maximum flow of compressed nitrogen gas (99.9%, but compressed air should suffice, being that air is ~80% nitrogen). Ive been out of the true engineering loop for a while, and my brain needs some direction. Most of the equations I have are for standard temp/pressure, where Im dealing with 25 psig through a 2" sch. 40 pipe.

Any help would be appreciated!

Thanks,

Clay
