RE: vapour pressure of crude oil LittleInch (Petroleum) 24 Jan 18 21:41 You need specific data. "Crude Oil" is a very wide spread and depends on how the crude is treated and heated. It is not a known or defined liquid like e.g. gasoline. Remember - More details = better answers Also: If you get a response it's polite to respond to it.
