What is the API gravity value of the oil?
between 15 and 45 degrees
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.
How do you find API 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.
What is the standard specific gravity of oil?
Specific Gravity Resource
| Liquid | SG @ 60°F / 15.6°C |
|---|---|
| Beer | 1.01 |
| Carbon Tetrachloride CCl4 | 1.59 |
| Corn Oil | 0.924 |
| Crude Oil | 0.79 – 0.86 |
What is API specific gravity?
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.
Why is API gravity important?
The API Gravity of a product is very important in determining the characteristics of the petroleum product. To learn more about this property, let’s apply the AmSpecapproach. API Gravity, or The American Petroleum Institute gravity, is a measure of how light or heavy a petroleum liquid is compared to water.
Is API and specific gravity the same?
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.
What is the highest API service rating for oil?
SM
The API’s current highest rating for motor oil is SM. This oil is intended for all gasoline engines currently in use and has been the standard since 2004. For diesel engines, the current top oil rating is CI-4.
Is API SN higher than SG?
SN oils provide higher levels of performance than all the other “S” oils.
What is API standard for oil and gas?
API is the worldwide leading standards setting body for the oil and natural gas industry. Accredited by the American National Standards Institute (ANSI), API has issued nearly 700 consensus standards governing all segments of the oil and gas industry.
Can I use API SP instead of API SG?
API SP will be fully backward-compatible with previous API service categories, including API SN PLUS, SN, SM, SL or SJ.
How do you convert API to specific gravity?
How do you convert density to API? Divide 141.5 by (131.5 + API gravity) to obtain the specific gravity of the oil. Continuing the example, divide 141.5 by 181.5 from the last step to get . 7796. Multiply the specific gravity of the oil by the density of water to obtain the density of the oil. Click to read further detail.
How do you calculate specific gravity of oil?
How do you calculate the specific gravity of crude oil? 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 API?
– The GET /?a=…&b=…&op=… method uses the query parameters to specify the input. – The POST / method uses a JSON payload of {“a”:”Number”, “b”:”Number”, “op”:”string”} to specify the input. – The GET /{a}/{b}/{op} method uses the path parameters to specify the input.
How to convert API gravity to density?
