650-I-11/02 Is there any allowance or provision to omit the top angle as required by API 650,220.127.116.11e and 18.104.22.168f if we can show by calculation that the top compression area is sufficient.No.3.2.4 9th - May 1993 Does API 650 cover the design of a tank for a design vacuum condition of 50 mm of water?The regular vent on a tank is just to let air in and out as the level moves up and down or the tank heats and cools. Usually,this will work outJStephen is quite correct (and succinct),as usual. Calculations based on pressure and flow are not needed,nor will they teach you anything.

Floating-roof tanks can be internal or external internal floating-roofs have a secondary fixed roof at the top of the tank to protect the floating element from rain and other outside contamination.External floating-roofs are exposed to the air and may be exposed to elements which may cause the roof to sink.
