Specifications: WITCOL RACER 4T is of the following quality level. API SL / SJ , JASO MA . It also meets VTW for API 2,5° API) obtained in the present work. Likewise, de Peinder and coworkers reported a RMSE of 0,005 g/mL for predicting density of crude blends from PLS 22 Apr 2015 of oil using hydrometer and density meter and to compare specific gravity and API gravity of different oils. In this experiment, to determine Buoyant force=Vpi*Df*g (Vpi=Volume of the particle immersed, Df=Density of the If the object has higher density than the fluid, it will sink otherwise it will float. Just use the density of oil instead of the density of water in the specific gravity Density is the primary characteristic when determining whether a liquid is gas or oil. The AER uses high and low liquid density thresholds to classify the liquid as
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)
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. The density of oil varies with API gravity of oil and the temperature conditions of the surroundings. It generally ranges from 0.91 to 0.93 gram per cubic centimeter when the temperature is between 15 and 25 degree Celsius. As the water is denser than oil it is found at the bottom while oil is found on the top of the water. API Gravity – Density Meter Application Report Understanding API Gravity: API Gravity – Crude oil is an indispensable starting material for all types of products and various other fuels, oils, and lubricants. Characterization of these products is most complex and often impractical. Subsurface density of oil or condensate depends on composition, amount of dissolved gases, temperature, and pressure. Oil or condensate density can be estimated to useful accuracy if stock tank API gravity and solution gas-oil ratio (GOR) are known. The American Petroleum Institute (API) is the only national trade association that represents all aspects of America’s oil and natural gas industry. Our more than 600 corporate members, from the largest major oil company to the smallest of independents, come from all segments of the industry. Definition of API Gravity at temperature: Estimate API Gravity at 60° F: 1) Usually, your API gravity reading will be at a temperature other than 60°F. To convert an API gravity reading to 60°F, we usually use ASTM Table 5B. The left and right margins of the table are annotated with the temperature.
The first step was to predict the heavy oil density from API and temperature for different crudes. The predicted values of the densities were used in the second
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
The equation for API gravity shows that a heavy oil has a relatively low API gravity because it has a large γo, while light oils have a relatively high API gravity . View
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. The relative density of petroleum liquids can also be uncovered by using API gravity value: RD at 60 o F = 141.5 / (API gravity + 131.5) A key formula for establishing barrels of crude oil per metric ton. Using the following formula, API gravity can also be used to calculate how many barrels of crude oil can be produced per metric ton. 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 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. The density of oil varies with API gravity of oil and the temperature conditions of the surroundings. It generally ranges from 0.91 to 0.93 gram per cubic centimeter when the temperature is between 15 and 25 degree Celsius. As the water is denser than oil it is found at the bottom while oil is found on the top of the water.

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.

This 8 Feb 2015 If the liquid's API gravity is less than 10 it will sink and falls into the heavy oil category. While API gravity essentially measures the relative density
