How do you convert API to specific gravity?

How do you convert API to specific gravity?

The formula for API gravity is API = (141.5/SG) -131.5 where SG is the specific gravity of the petroleum liquid being measured. For example, for an API gravity of 50, add 131.5 to obtain 181.5. Divide 141.5 by (131.5 + API gravity) to obtain the specific gravity of the oil.

How do you calculate specific gravity of fuel oil?

Using the API to Specific Gravity Conversion formula, the oil specific gravity is calculated: SG(oil) = 141.5 / (°API+131.5) = 141.5 / (35+131.5) = 0.845….Example:

  1. Oil Gravity: 35 API,
  2. Water Cut: 90%,
  3. Water Gravity: 1,01 rel-H2O,

What is the specific gravity of lube oil?

Specific Gravity Resource

Liquid SG @ 60°F / 15.6°C
Machine Lubricants 0.88 – 0.94
Milk 1.02 – 1.05
Peanut Oil 0.92
Propylene Glycol 1.038

What is the relation between API gravity with density of oil?

API gravity is a commonly used index of the density of a crude oil or refined products. API stands for the American Petroleum Institute, which is the industry organization that created this measure. A crude oil will typically have an API between 15 and 45 degrees. Higher API indicates a lighter (lower density) crude.

What is the density of lube oil?

between about 700 and 950 kg/m3
Density. Density means the volume weight of a substance. In oils, it is usually indicated in the temperature of +15°C or +20°C, in units kg/m3. Lubricant densities range between about 700 and 950 kg/m3, depending on the quality, viscosity and additive content of the lubricant.

What is the weight density of oil?

The density of most oils will range between 700 and 950 kilograms per cubic meter (kg/m3).

Is API gravity the same as density?

What is the relationship between API and specific gravity?

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.

How is density related to gravity?

Density is defined as mass per unit volume. It has the SI unit kg m-3 or kg/m3 and is an absolute quantity. Specific gravity is the ratio of a material’s density with that of water at 4 °C (where it is most dense and is taken to have the value 999.974 kg m-3). It is therefore a relative quantity with no units.

How specific gravity is related to density?

Specific gravity is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material, often a liquid. If a substance’s relative density is less than one then it is less dense than water and similarly, if greater than 1 then it is denser than water.

How do you calculate the density of oil?

In Layman’s terms, density is the mass of an object relative to the volume it occupies. Mathematically, density, mass and volume are related according to the following formula: ρ=m/V where ρ=density, m=mass and V=volume. The density of most oils will range between 700 and 950 kilograms per cubic meter (kg/m3).

Is density the same as specific gravity?

How do you convert density to weight?

Multiply the specific gravity by 1,000 to calculate the density of the substance in kilograms per cubic meter (kg/cubic meters) units. For example, the specific gravity of 0.84 corresponds to the density of 840 (0.84 x 1000) kg/cubic meters.

Is density directly proportional to gravity?

Density is directly proportional to acceleration due to gravity.
