If you are like me you would have thought you were done with algebra once you received your diploma. I am quickly discovering that is not the case. I've received paperwork from the manufacturer and there is a formula that uses an "MCF" or cost per 1000 cubic feet of air. I don't have a formula anywhere. Does anyone have this or am I missing something?

Here is a reference that may help:

I assume you are investigating/justifying ultrasound for leak detection and are trying to estimate the potential savings.

Here's the one from UE systems that I used. It may not be as detailed as Walt's but pretty simple without alot of algebra. (I failed algebra my first time)
