API Gravity 02


API Gravity 02 :

(n.) Enhanced Oil Recovery, Heavy Oil. A specific gravity scale developed by the American Petroleum Institute (API) for measuring the relative density of various petroleum liquids, expressed in degrees. API gravity is gradated in degrees on a hydrometer instrument and was designed so that most values would fall between 10o and 70o API gravity. The arbitrary formula used to obtain this effect is: API gravity = (141.5/SG at 60o F) - 131.5, where SG is the specific gravity of the fluid
