The generic meaning for atmosperic pressure is up to but not exceeding _______ ibf/in2 gage pressure. 2.5 The exterior surface of the tank bottom is known as the : bottom- side. When describing the amount of product the tank can hold, it is referred to as: shell capacity The pressure on the surface of a confined liquid caused by the vapors of that liquid is known as: vapor pressure A device that protects atmospheric storage tanks by maintaining the pressure difference between the tank vapor space and the outside atmosphere to just a few ounces per square inch is called : a pressure vacuum vent. The most common type of atmospheric storage tank is the fixed : cone-roof tank. An older style of a floating roof has only a single deck without pontoons.
