Paul,
What would the pressure or speed in knots of .05" h2O be? I have a
pressure switch marked such. How would you figure it?
About 15 mph or 13 kts?

Marc Wiese

Impact pressure in pounds per square foot = MPH squared times .0026
One cubic foot of water weighs 65 pounds so 12 inches of water is
.45 psi. One inch of water is .0376 psi
