API gravity — The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water. If its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and… … Wikipedia
API gravity — An arbitrary scale expressing the gravity, or density, of liquid petroleum products in terms of API degrees. Relationship of the API scale to specific gravity is expressed by the equation ºAPI = (441.5/sp gr 60/60F) 131.5. ASTM D 287 is the… … Petroleum refining glossary
API Gravity — Universally accepted scale, adopted by the API, to express the specific gravity of oils. It serves as a rough measure of quality. The higher the API gravity number, the richer the yield in premium refined products. ► See also API … Financial and business terms

API gravity — noun A specific gravity scale measuring the relative density of various petroleum liquids, expressed in degrees … Wiktionary
API (disambiguation) — API, originally Advanced Programming Interface but now more commonly known by its near synonym, Application programming interface, is any defined inter program interface.API or api may also refer to:* Api (mountain), a mountain in Nepal * API… … Wikipedia
Gravity (chemistry) — In chemistry, gravity is the density of a fluid, particularly a fuel. It is expressed in degrees, with lower numbers indicating heavier liquids and higher numbers indicating lighter liquids. See specific gravity and API gravity … Wikipedia
API oil-water separator — An API oil water separator is a device designed to separate gross amounts of oil and suspended solids from the wastewater effluents of oil refineries, petrochemical plants, chemical plants, natural gas processing plants and other industrial… … Wikipedia
Плотность в градусах API — Плотность в градусах API единица измерения плотности нефти, разработанная Американским институтом нефти. Измерения в градусах API позволяют определить относительную плотность нефти по отношению к плотности воды при той же температуре. По… … Википедия
Densité API — La densité API est une échelle permettant d exprimer la densité du pétrole brut, en degrés API (° API), calculée à partir de la densité, par la formule suivante : Densité API = (141.5/(densité à 60 °F)) – 131.5 Plus un brut est léger, plus… … Wikipédia en Français
