Why API gravity is used instead of specific gravity for petroleum fuels?
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.
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.
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.
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.
What does API mean in oil and gas?
American Petroleum Institute
The API (American Petroleum Institute) number is a unique number assigned to every oil and gas well. It is used by agencies to identify and track oil and gas wells.
What is API mention the application of API in the petroleum?
The American Petroleum Institute (API) is the largest U.S. trade association for the oil and natural gas industry. It claims to represent nearly 600 corporations involved in production, refinement, distribution, and many other aspects of the petroleum industry.
What is the API gravity of a substance with specific gravity 1?
SG – API Converter
| Degree API | Specific Gravity | Weight |
|---|---|---|
| [lb/US gal] | ||
| 1 | 1.068 | 8.894 |
| 5 | 1.037 | 8.633 |
| 8 | 1.014 | 8.447 |
What does API gravity measure?
A measurement convention established by the American Petroleum Institute for expressing the relative density of petroleum liquids to water; the greater the API gravity, the less dense the material.
What is an API number in oil?
The API (American Petroleum Institute) number is a unique number assigned to every oil and gas well. It is used by agencies to identify and track oil and gas wells. Every oil and gas well permitted in West Virginia since 1929 has been issued an API number.
Why are API standards important?
Consistently designed APIs ensures the implementation team, be it developers, devOps or testers, can work better on creating a functioning API. Creating clean, easy to understand and relatable design standards ensures every stakeholder within the team knows what to do with the API.
What does API stand for in oil and gas?
What is the difference between API and specific gravity?
Specific gravity is a ratio of the density of one substance to the density of another reference substance, which is usually water. API gravity itself is a specific-gravity measurement used by the oil industry to compare an oil’s density to that of water.
How do you convert API to specific gravity?
To convert from specific gravity to API, divide 141.5 by the specific gravity, then subtract 131.5. The specific gravity that should be used is that from oil at sixty degrees Fahrenheit.
How do you calculate 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 that seems arbitrary, it is because the equation was designed for convenience’s sake.
What is meant by API gravity?
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.
