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...
