Re: Water Column



Let's see if I can calculate it :

40 inches / 12 = 3.333 Head feet.

3 HF = 1.203 P.s.i.
..3 = 1.302 * .1 = .1302
..03 = 1.302 * .01 = .01302

Therefore 40 inches = 3.33 Head feet = 1.346 psi If I did it correctly.

Water is 62.5 # / cu ft.

As an example, 85.3 ft is 37.02 p.s.i.

Hello, my question is, dose any one know how much p.s.i. 40 inches of water
column is? We made some pipe at work which is attached to a rather large fan
and the air going through it is measured in water column and being a welder
I relate to every thing in p.s.i. I would like to know if it a lot of
pressure? Thank you Ed
