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 sinks.

Its typical gravity is around 80 API. Natural gasoline is rather volatile and unstable, and has a low octane rating, but can be blended with other hydrocarbons to produce commercial gasoline. [4] It is also used as a solvent to extract oil from oil shale. [4] Its properties are standardized by GPA Midstream (formerly Gas Processors Association ...
The clear cut definition of light and heavy crude varies because the classification is based more on practical grounds than theoretical. The New York Mercantile Exchange (NYMEX) defines light crude oil for domestic U.S. oil as having an API gravity between 37° API (840 kg/m 3) and 42° API (816 kg/m 3), while it defines light crude oil for non-U.S. oil as being between 32° API (865 kg/m 3 ...
Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°. [2] Physical properties that differ between heavy crude oils and lighter grades include higher viscosity and specific gravity, as well as higher molecular weight hydrocarbon composition.
API RP 500 and RP 505 classify the locations for electrical equipment in hazardous areas. [14] [15] API has entered petroleum industry nomenclature in a number of areas: API gravity, a measure of the density of petroleum. API number, a unique identifier applied to each petroleum exploration or production well drilled in the United States.
Traditionally, VCF / CTL are found by matching the observed temperature and API gravity within standardized books and tables published by the American Petroleum Institute. These methods are often more time-consuming than entering the values into a VCF calculator; however, due to the variance in methodology and computation of constants, the ...
A fuel station in Zigui County on the Yangtze River HAZMAT class 3 fuel oil. Oil has many uses; it heats homes and businesses and fuels trucks, ships, and some cars.A small amount of electricity is produced by diesel, but it is more polluting and more expensive than natural gas.
