I'm designing an API 650 tank and the governing venting requirements are from API 2000. There are a number of venting requirements from API 2000 (liquid from pumps, thermal, and emergency), but the one I have a question about it emergency venting. If the contents of the tank are not hydrocarbons (i.e. water for example), would the emergency venting still apply? I'm a mech (BE) and structural (ME), so my chemistry classes are a distant memory, but my gut feeling is telling me a tank full of water subject to fire would expire vapor at a lesser rate than a tank full of gasoline subject to the same fire. Am I correct in that assumption? If so, how do I "factor down" the volumetric flow rate to account for the less volatile contents?
Many thanks for any responses.
