Specific gravity (sp gr) measures the ratio of density of the substance to the density of water in a given temperature, (i.e., 4 o C). 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. 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 and API gravity are both measurements of density. They both can be used to measure the gravity of a fluid, such as hydraulic oil, in the same way that miles or kilometers can both be used to measure distance. And just like kilometers and miles, neither is more accurate than the other; deciding which Specific Gravity and Density. 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 The composite specific gravity of oil and water mixture can be calculated if the individual fluid’s specific gravities and percentages are known. The specific gravity of this mixture is calculated as shown in the following equation: SG comp = [SG o × (1 – WC)] + (SG w × WC)

Oil Specific Gravity = 0.88 (54.88 lb / ft3); Gas to Oil Ratio = 950 SCF/bbl; Water Cut = 75%. Black_Oil_11.png. Note that the Gas to Oil Ratio Oil gravity relates the density of oil to that of the density of water. The American Petroleum Institute (API) developed a specific gravity scale that measures the Specific gravity (or relative density) is the ratio, at a specified temperature, of the oil density to the density of pure water. The API gravity scale arbitrarily assigns an What this means is that most oils will float on water as they are lighter by volume. Below is a chart displaying how API relates to specific gravity and weight per 13 Mar 2018 This follows from the formula of specific gravity where SG = density(oil)/density( water). Concluding the example, .7796 * 1 grams per cubic continuous liquid, specific gravity difference between the continuous liquid, and the oil droplet size. After these are known, the rising velocity and therefore the 8 Feb 2015 measures the relative density of petroleum liquid and water it is primarily used Barrels of crude oil per metric ton = 1 / [141.5 / (API gravity + 131.5) x 0.159] Used in conjunction with the specific-industry API Gravity scale,
Specific gravity of diesel fuel oil is a comparison of its density with that of pure water. According to Simetric, the density of pure water at 4 degree centigrade is considered as the baseline for specific gravity; so its specific gravity is 1. The density of diesel fuel oil (20 to 60) at 15 degree centigrade is found to be in the range of 820
Because water at 4 degrees Celsius is the standard scientists use to determine specific gravity, it follows that its specific gravity is 1. However, a water sample at a different temperature or pressure or one containing impurities has a density that differs slightly. Specific gravity is the heaviness of a substance compared to that of water, and it is expressed without units. In the metric system specific gravity is the same as in the English system. If something is 7.85 times as heavy as an equal volume of water (such as iron is) its specific gravity is 7.85.

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. In the oil
The reference substance is nearly always water at its densest (4°C) for liquids; for gases it is air at room temperature (21°C). Nonetheless, the temperature and 5 Sep 2018 Our AquaSweep™ Gravity Oil Water Separator is UL 2215 Listed and and related petroleum products with a specific gravity of less than 1.0. are provided so that the oil and inci dental suspended solids separate from the water by differences in specific gravity. As the separation is obtained. where go +oil specific gravity (water+1). Officially, the SPE does not recognize gAPI in its SI standard, but because oil gravity (in de- grees API) is so widely used of 1. Most oils are less dense or lighter than sea water which typically has a specific gravity of about 1.025. The American.
