assume submersible centrifugal pumps, in water wells

assume in the range of 40 to 60 psi.

Think that makes sense, please see sketch to see if I am interpretating correctly:

thanks for the reply, i added more info / a question below in the thread.

thanks for the reply, i added more info / a question below in the thread.

real life application. Trying to conceptualize to start things off before looking at real flows and real header distances / head losses. For example, does P.1 need to just be able to do 40 gpm and the total head from P.1 to Pond, P.2 needs 40 gpm and total head from p.2 to pond, P.3 needs 40 gpm...

Three wells each pump 20 gpm to a combined header. What is the correct way to size pumps 1, 2, and 3 (with respect to head, flow) considering this configuration shown in sketch?

Haha. The purpose would be to stimulate/enhance aerobic microorganisms that break down contaminants

You very well may be right... however, this is my current scenario.. quick sketch attached!

The concept of the anemometer is similar; however, put a funnel on the one end, add a hollow stem, and check valve. If it helps, the objective is to inject air (wind assisted, very low flow) through a check valve (trying to figure out design parameters) and into the soil column.

The funnel (lets say inlet diameter 18", 20 degree reducing to 2" outlet) spins freely to capture the prevailing wind (fluid is air, wind speeds of 10 - 20 mph). the outlet connects to a one-way check-valve with low (i.e., 0.5 psi) cracking or opening pressure. The question is can the low...

Imagine a wind speed of 'W' (variable), rotating funnel of 'X' diameter that narrows and then conveys flow through a 'Y' diameter, 'Z' length pipe until it hits a 'Y' diameter check valve. What is the minimum cracking pressure needed of the check valve, provided the variables above? I am...
