What is the formula for API?

What is the formula for 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.

How do you convert specific gravity to API?

How to estimate API gravity?

  1. Divide 141.5 by the specific gravity of the liquid.
  2. Subtract 131.5 from the resultant to obtain the API gravity.

How do you calculate the API gravity of crude oil?

The official formula used to derive the gravity of petroleum liquids from the specific gravity (SG), as follows:

  1. API gravity = 141.5/SG – 131.5.
  2. RD at 60oF = 141.5 / (API gravity + 131.5)
  3. Barrels of crude oil per metric ton = 1 / [141.5 / (API gravity + 131.5) x 0.159]

Is API the same as 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.

What is the API of heavy oil?

A medium crude is in the 25-35 API range, and a heavy crude is in the 15-25 API range. Anything below 15 API would be considered an extra-heavy crude.

What is the API of water?

10°

petroleum industry, however, uses the American Petroleum Institute (API) gravity scale, in which pure water has been arbitrarily assigned an API gravity of 10°. Liquids lighter than water, such as oil, have API gravities numerically greater than 10.

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 the API gravity of water?

… petroleum industry, however, uses the American Petroleum Institute (API) gravity scale, in which pure water has been arbitrarily assigned an API gravity of 10°. Liquids lighter than water, such as oil, have API gravities numerically greater than 10.

What is the specific gravity of 38 API oil?

What is the API of heavy crude oil?

How is API measured?

The most basic set of API metrics is operational. They measure API performance, such as the number of APIs, the number of API calls, CPU or memory usage. Operational metrics give an indication of the operational stability of an API platform.

What is API oil classification?

The service rating of passenger car and commercial automotive motor oils is classified by the American Petroleum Institute (API). The program certifies that an oil meets certain Original Equipment Manufacturer (OEM) quality and performance standards.

What is API range?

The API of crude oils varies typically between 10 and 50, with most crude oils falling in the range of 20-45. Using API gravity, the conventional crude oils can be generally considered as light (°API>30), medium (30>°API>22), and heavy (°API<22).

What is standard API?

The Standard API is a REST API between client apps and the EVRYTHNG Platform. It is used to create and manage projects, applications, products, thngs, actions, and more platform resources. This API Reference section of the Developer Hub contains sections for each module of the API.

Does API gravity have units?

The widely used American Petroleum Institute (API) gravity scale is based on pure water, with an arbitrarily assigned API gravity of 10°. (API gravities are unitless and are often referred to in degrees; they are calculated by multiplying the inverse of the specific gravity of a liquid at…

What is the API of diesel fuel?

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. (See Chapter 4 – Diesel Fuel Refining and Chemistry for an explanation of fuel blending, density, and API gravity.)

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 API means?

Application Programming Interface
API stands for Application Programming Interface. In the context of APIs, the word Application refers to any software with a distinct function. Interface can be thought of as a contract of service between two applications. This contract defines how the two communicate with each other using requests and responses.

What’s the highest API rating for oil?

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.

What is API CI-4 oil?

API CI-4 oils are pivotal components in maintaining diesel engine durability using cooled EGR. API CI-4 is a higher quality oil than the previous diesel oil categories, so it will provide engine protection for both existing and new EGR engines.

What is API example?

APIs are mechanisms that enable two software components to communicate with each other using a set of definitions and protocols. For example, the weather bureau’s software system contains daily weather data. The weather app on your phone “talks” to this system via APIs and shows you daily weather updates on your phone.

What is an API in simple terms?

API is the acronym for Application Programming Interface, which is a software intermediary that allows two applications to talk to each other. Each time you use an app like Facebook, send an instant message, or check the weather on your phone, you’re using an API.

What is API gravity of water?

… petroleum industry, however, uses the American Petroleum Institute (API) gravity scale, in which pure water has been arbitrarily assigned an API gravity of 10°.

What is the highest API 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.

What is No 2 diesel fuel?

No. 2 Diesel Fuel. A fuel that has distillation temperatures of 500 degrees Fahrenheit at the 10-percent recovery point and 640 degrees Fahrenheit at the 90-percent recovery point and meets the specifications defined in ASTM Specification D 975.
