I am trying to figure out how to size an open-air vent for a 33,000 gal, vertical atmoshperic tank. There is a known liquid flow in and out of the tank (not always equal), as well as a known air flow into the tank. I keep thinking that one way to do this is to know (which I don't) what velocity the air should be as it leaves through the vent, then figure the balnce, therefore the proper size, volumetrically. But, I can not find a value given anywhere. The API standards to not give such information. I appreciate any and all help.
PS. The liquid involved with the tank is not flammable, so there is no need for emergency venting.
