## Determination of specific gravity of crude oil

Specific gravity is calculated as the ratio of the density of a liquid to the density of water. So any liquid with a density greater than water has a specific gravity greater than 1. Liquids with a density lower than water, which includes most crude oil grades and petroleum products, will have a specific gravity between 0.0 and 1.0. Calculation of API gravity. API is calculated from a hydrocarbon's specific gravity using this formula: API = (141.5/Specific Gravity) - 131.5. API gravity of crude oil grades. A crude oil will typically have an API between 15 and 45 degrees. Higher API indicates a lighter (lower density) crude. Lower API indicates a heavier (more dense) crude. Oil density. The physical property density is the ratio between mass and volume. The density of crude oil can be determined from : Specific gravity of the crude oil. Solution gas gravity. Solution gas-oil ratio. Oil formation volume factor (FVF).

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.. API gravity is thus an inverse measure of a petroleum liquid's density relative to that of water (also known as specific gravity). Specific gravity is calculated as the ratio of the density of a liquid to the density of water. So any liquid with a density greater than water has a specific gravity greater than 1. Liquids with a density lower than water, which includes most crude oil grades and petroleum products, will have a specific gravity between 0.0 and 1.0. Calculation of API gravity.

A crude oil will typically have an API between 15 and 45 degrees. Higher API indicates a lighter (lower density) crude. Lower API indicates a heavier (more dense) crude. Oil density. The physical property density is the ratio between mass and volume. The density of crude oil can be determined from : Specific gravity of the crude oil. Solution gas gravity. Solution gas-oil ratio. Oil formation volume factor (FVF). Specific gravity of a liquid is the ratio of the density of the liquid at 60°F to the density of pure water. API gravity is related to the specific gravity by the following equation: The specific gravity of a gas is the ratio of the density of the gas to the density of air at standard conditions of temperature and pressure. laboratory determination of API gravity/SG of crude oil using glass hydrometer. DEFINITION The specific gravity of a liquid is. defined as the ratio of the mass of a given volme of a liquid at temperature to the mass of an equal volume of pure water at a temperature. ie SG oil=density of oil/density of water.

## API gravity express the gravity or density of crude oil and liquid petroleum products. API is devised jointly by the American Petroleum Institute and the NIST - National Institute of Standards and Technology.The measuring scale is calibrated in terms of degrees API. API Gravity can be calculated as:

One of the most important physical properties of crude oil is its specific gravity — the is determined by the time it takes for 60 cm3 of crude oil to flow by gravity  and Laboratory Procedures for the Determination of Methane, Carbon Dioxide, and conditions. Crude oil has an API Gravity equal to or less than 40. molecular weight of those compounds, API Gravity, and Specific Gravity of the decanes  If you need need to convert other value use our online Api Gravity Calculator. Specific Gravity of Crude Oil: They are many common crude types like west Texas, Brent… API gravity is a measure of how light or heavy the crude oil compared to water.
