Thanks for the replies.
1- Ingersoll Rand isn't open on the weekend and I'm trying to put a budget together for a new shop for a meeting Monday morning, so just trying to get close.
2- Thanks for all the work but that doesn't help as I don't have the compressor to test. I'm trying to spec a new compressor and can't buy more than I need right now.
I found this formula online and it seems to make sense.
P=K*(1/V)
90psi=K*(1/5cfm)
Solving for K, we get a value of K= 450
V=K*(1/P) so V=450*(1/35psi)= 12.86 cfm
So my situation works like this I think assuming the manufacturers specs of 175psi and 14 CFM:
175=K(1/14)
K=2450.9
so
V=2450(1/100)
V=24.5
I think that seems right if I have 14 CFM at 175 then this says I'd have 24.5 CFM at 100.
Which is just about perfect for what I need. So I don't need to go up to a compressor larger than this 5hp 80 gallon which would be a lot more money.
