How do you calculate API?
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 the API gravity of crude oil?
API stands for the American Petroleum Institute, which is the industry organization that created this measure.
- Calculation of API gravity.
- API = (141.5/Specific Gravity) – 131.5.
- API gravity of crude oil grades.
What is API in fuel?
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. It is used to compare densities of petroleum liquids.
What is API scale?
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.
What is API gravity of diesel?
The API gravity at 60°F (15.6°C) for No. 2 diesel fuel is between 30 and 42. The specific gravity, at 60/60°F, and the density, at 15.6°C, are between 0.88 and 0.82.
How do you convert specific gravity to API?
API gravity can be estimated by the following method:
- Divide 141.5 by the specific gravity of the liquid.
- Subtract 131.5 from the resultant to obtain the API gravity.
What is API gravity and how is it calculated?
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. The arbitrary formula used to obtain this effect is: API gravity = (141.5/SG at 60 degF) – 131.5, where SG is the specific gravity of the fluid.
What is API value?
An API value chain is a series of transformation processes that create value in the API economy. APIs enable digital value chains. That’s because APIs are a critical part of the digital transformation strategy of any business. They help you transform data, enable multicloud strategy, and accelerate time-to-market.
What is API rating for oil?
API stands for the American Petroleum Institute. The organization evaluates every blend of motor oil. It assigns an API rating to motor oil blends that meet ILSAC’s current standards. ILSAC stands for International Lubricant Standardization and Approval Committee.
What is API gravity scale?
What is the API of heavy oil?
Although variously defined, the upper limit for heavy oils has been set at 22°API gravity and a viscosity of less than 100 cP. The portion of heavy oil having an API gravity of less than 10°. Also known as “oil sands,” bitumen shares the attributes of heavy oil but is even more dense and viscous.
How to convert g / mL to kg / m3?
How to convert from g/mL to kg/m3, which are both units of density. Quick way: multiply by 1000. In the video I show you the “full solution” way if you have to show your work.
How to convert kilogram / cubic meter to Gram?
To convert between Kilogram/cubic Meter and Gram/milliliter you have to do the following: First divide 1/1 / 0.001/0.000001 = 0.001 Then multiply the amount of Kilogram/cubic Meter you want to convert to Gram/milliliter, use the chart below to guide you. KILOGRAM/CUBIC METER TO GRAM/MILLILITER (kg/m³ TO g/ml) CHART
How is the gravity of an oil calculated from API?
Specific gravity can be calculated from API gravity: SG = 141.5 / (°API+131.5) (2) Note! Oil with the least specific gravity has the highest API gravity.
