## Oil api density

API gravity is thus an inverse measure of a petroleum liquid's density relative to that of water (also known as specific gravity). It is used to compare densities of petroleum liquids. For example, if one petroleum liquid is less dense than another, it has a greater 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 sinks. API gravity is thus an inverse measure of a petroleum liquid's density relative  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   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)  The API gravity is nothing more than the standard specific gravity used by the oil industry, which compares the density of oil to that of water through a calculation  13 Mar 2018 Add 131.5 to the API gravity. The formula for API gravity is API = (141.5/SG) - 131.5 where SG is the specific gravity of the petroleum liquid being  Density, specific gravity (SG) and API gravity* values are used to monitor quality during the production of crude oil, and to establish its price in trading.

°API. Density is a temperature depedent property. API gravity increases with increasing temperature, while specific gravity decreases with increasing temperature. See correlations at Density of crude oil as function of temperature. This means that the volume of a petroleum liquid increases with increasing temperature, and that a density number always must be given with the measurement temperature. The standard measuring temperature is 15°C or 60°F. API gravity is thus an inverse measure of a petroleum liquid's density relative to that of water (also known as specific gravity). It is used to compare densities of petroleum liquids. For example, if one petroleum liquid is less dense than another, it has a greater API gravity. 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. The American Petroleum Institute established API gravity measure as a measure of the density of petroleum liquids relative to water. The greater the API gravity, the less dense the liquid. The scale of API gravity was adjusted so that most petroleum liquids fall between 10 and 70 degrees API gravity. API gravity is measured as the inverse of the density of a petroleum liquid relative to water. The higher the API gravity, the lower the density of the petroleum liquid, so light oils have high API gravities. Density is defined as mass per unit volume of a fluid. The density of crude oil and liquid hydrocarbons is usually reported in terms of specific gravity (SG) or relative density, defined as the density of the liquid material at 60°F (15.6°C) divided by the density of liquid water at 60°F.

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 calculated using the specific gravity of an oil, which is nothing more than the ratio of its density to that of water (density of the oil/density of water). Specific gravity for API calculations is always determined at 60 degrees Fahrenheit. API gravity is found as follows: API gravity = (141.5/Specific Gravity) – 131.5 It is a dimensionless unit. Oil gravity differs for each liquid. Use the online API to Specific gravity converter to find the Sp gr of an oil by providing the API gravity. API is measure of the density of a petroleum liquid when compared with the water. In the Density vs temperature figure(°C), you se that the light grey line represent this crude oil. Then, use the light grey line in the Crude oil volume correction figure (Density@Observed T/Density@15°C). At 50°C the correction factor is 0.965. The volume of your crude oil at 15°C is 100liters*0.965 = 97 liters. (Easy check: Lowest volume at the lowest temperature) 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 10° and 70° API gravity. API gravity is thus an inverse measure of the relative density of a petroleum liquid and the density of water, but it is used to compare the relative densities of petroleum liquids. For example, if one petroleum liquid floats on another and is therefore less dense, it has a greater API gravity.
