Hi,
I was wondering if you used some sort of formula for the chart you provide for the water
manometer, can I get it from you? I want to extend the chart for lower speed ranges.

The impact pressure formula I use is pounds per square foot = .0026 X MPH^2

One inch of water is .037 psi.

BTW I will start to use the term "impact pressure" rather than
"dynamic pressure" as I think "impact pressure" is more descriptive.
