Is there any chance that anyone would be willing to help get me started on the derivation? It's been a while since I've done any hydro calcs. What I can supply is that this is in a water tower (as I think I mentioned). The top of the tower has a vent on it which leads to the atmosphere...

Oh wow, yeah, sorry about that. They're pretty standard parameters: Av = required area of the vent (ft^2) Ce = entry coefficient (unitless) Q = flow rate (GPM) pressure diff = the meaning of this is still a bit fuzzy to me (" H20)

I'm looking at a vent that will be used to prevent a tank from collapsing due to vacuum pressures in a pipe burst/free drain scenario. The situation would be a container is filled with water when an inlet or an outlet pipe bursts. The water flowing out would create some pressure in the tank...
