Hello all,(adsbygoogle = window.adsbygoogle || []).push({});

I am new to this site and was hoping someone could help me.

I run into this kind of problem annually. And my boss usually has me spend a boat load of money by oversizing pnuematic pipe "just to be safe".

What I need to know is, how much cfm will a 150 ft long 1" copper pipe deliver at 95psi?

There has to be a way to calculate if there is enough capacity in an existing line when installing new equipment. I'd like to know how to do this before running a third line to the same room.

The equiment we're installing will require (per mfr) 90cfm. Any advise would be greatly appreciated.
