Hoping someone that knows about this can enlighten me .
In the following pic ( sorry about the midnight texta special ) .A Bunnings pump in a tank ....feeds a PC and on the way back to the tank is a venturii setup .
I really don't understand this principle , but am I correct that the tube in question would have a sucking effect on it or would water be blown out it .
If it does have a sucking effect ,is there some angle or diameter or whatever that makes this happen ?
If there is a sucking effect ,would it intake water or just air ?
