## Specific gravity of oil calculation

Calculating API Gravity. To calculate API gravity, you need to know the fluid's specific gravity. Divide 141.5 by the fluid's specific gravity and subtract 131.5. If gasoline, diesel, fuel oil and crude oil, it was observed that a significant problems and in other cases the necessary calculations and conversions A number of density (or Specific Gravity or API) test methods are discussed in this report.

They calculated the coefficients in the viscosity equation as a function of the oil fractions characterization parameters. Their method only needs the specific gravity 25 Apr 2019 the correlation which I use is 141.5 / Specific Gravity - 131.5 where Specific Gravity = crude oil density / 999 where liquid density is the density The oil gravity has a very strong effect on the calculated oil The American Petroleum Institute (API) developed a specific gravity scale

## Specific gravity can be calculated from API gravity: SG = 141.5 / (°API+131.5) (2)

Simple method to determine specific gravity or particle density - Duration: 2:07. DrDirtSoilVideos 93,633 views The additional data requirements for NAPLs include: (1) fluid specific gravity (density), (2) fluid viscosity, (3) residual saturation, (4) relative permeability-saturation-capillary pressure relationships, and (5) NAPL thickness and distribution. Specific gravity is a unitless measurement that is derived as a ratio of either the weight of another liquid or the density of another liquid divided by the weight or density of water. Temperature must also be taken into account when determining specific gravity, since density changes in relation to temperature. Specific gravity has no units because it’s a ratio of density divided by density, so all units cancel out. Therefore, the specific gravity of gold is simply 19.3. Anything with a density greater than 1,000 sinks in pure water at 4 degrees Celsius, and anything with a density less than 1,000 floats.

### 22 Dec 2015 The formula for specific gravity, given that the reference substance is water, is the density of the object divided by the density of the water. Here

The formula to obtain API gravity of petroleum liquids, from specific gravity (SG), is: Using API gravity to calculate barrels of crude oil per metric ton. In the oil You need two quantities to calculate the Sp.G. of your unknown mineral: the mass of the sample, and its volume. 1. The day before, The gas specific gravity calculation does not check for unreasonable inputs. Please enter positive values. Equations for Ideal Gas Law Calculator (CRC, 1983 ).

### In physics, a substance’s specific gravity is the ratio of that substance’s density to the density of water at 4 degrees Celsius. Because the density of water at 4 degrees Celsius is 1,000 kg/m3, that ratio is easy to find. For example, the density of gold is 19,300 kg/m3, so its specific gravity is the […]

Specific gravity is calculated by dividing the density of a fluid by the density of water. As you may know, if something is denser than water, it sinks, while if it is less dense than water, it floats. So if a fluid's specific density is higher than 1, it will sink, but if it is less than 1, it will float. Specific gravity can be calculated from API gravity: SG = 141.5 / (°API+131.5) (2) Remember that we can calculate specific gravity using the masses of the object and reference liquid so we don't need to convert anything. We just divide the mass of the object -- that's 180 lbs. -- by the mass of the water it's in which is 70 lbs. That gives us a specific gravity of 2.6. 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 formula to calculate API gravity from Specific Gravity (SG) is: API gravity = 141.5 SG − 131.5 {\displaystyle {\text{API gravity}}={\frac {141.5}{\text{SG}}}-131.5} Conversely, the specific gravity of petroleum liquids can be derived from their API gravity value as In physics, a substance’s specific gravity is the ratio of that substance’s density to the density of water at 4 degrees Celsius. Because the density of water at 4 degrees Celsius is 1,000 kg/m3, that ratio is easy to find. For example, the density of gold is 19,300 kg/m3, so its specific gravity is the […] Specific Gravity of gases is normally calculated with reference to air - and defined as the ratio of the density of the gas to the density of the air - at a specified temperature and pressure. The Specific Gravity can be calculated as . SG = ρ gas / ρ air [3] where SG = specific gravity of gas ρ gas = density of gas [kg/m 3]
