I know there is a simple formula or answer to this question.

I have an air compressor that provides 9.6cfm at 90psi.

I am running an a pneumatic tool that is rated 3cfm at 90psi.

I have a hose reel with 100 feet of 3/8 hose. I notice the tool does not run at optimum and I must pause frequently. This morning I replaced the 100 feet of hose with a 20 foot piece of 3/8 hose and the tool worked very well.

So here is my question:

I know there is a formula or a calculation to determine the loss of CFM as the hose length increases. Can anyone enlighten me?

Thank,
