Great help thank you very much.
Yes, normally I would just size the vent according to the piping and I use a Greenheck vent (which in their literature gives me the pressure convegence for their vents) I have an Owner who wants just "basically" a screen put up. So I was stuck on the pressure...
Hi there, I am new to eng-tips and pretty excited about what I see so far. I would appreciate any help with my question.
I am sizing a vent for a water tank. It has a maximum outflow of 90,000 gallons per minute.
I need the pressure differential to be less than 2 inches however, I am not sure...
