Crude oil api gravity calculator
API sets the standards for oil & gas industry. this article touches on the API gravity number, how it is calculated, the story behind using it, a list of crude oil blends and benchmarks, and the formulas associated with calculating API gravity API gravity. 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.. Calculation of API gravity. API is calculated from a hydrocarbon's specific gravity using this formula:. API = (141.5/Specific Gravity) - 131.5 γ API = oil API gravity γ g = gas specific gravity, air=1 γ gc = gas specific gravity adjusted for separator conditions, air=1 γ ghc = gas specific gravity of hydrocarbon components in a gas mixture, air=1 γ gs = separator gas specific gravity, air=1 γ o = oil specific gravity μ o = oil viscosity, m/Lt, cp μ ob = bubblepoint oil Generally speaking, oil with an API gravity between 40 and 45 commands the highest prices. Above 45 degrees the molecular chains become shorter and less valuable to refineries. [1] Crude oil is classified as light, medium or heavy, according to its measured API gravity. Light crude oil is defined as having an API gravity higher than 31.1 °API.
A specific gravity scale developed by the American Petroleum Institute (API) for The arbitrary formula used to obtain this effect is: API gravity = (141.5/SG at
API gravity is a measure of the density of crude oil as compared to density of water use EnggCyclopedia's liquid density calculator to evaluate water density at 1 Apr 2014 Changes in crude oil density and specific heat, or heat capacity, can However; use of the data in subsequent calculations requires users to interrupt the calculation, Figure 1A Crude Oil Specific Gravity vs Temperature (1). D1298-12b(2017) Standard Test Method for Density, Relative Density, or API Gravity of Crude Petroleum and Liquid Petroleum Products by Hydrometer Method A specific gravity scale developed by the American Petroleum Institute (API) for The arbitrary formula used to obtain this effect is: API gravity = (141.5/SG at D287-12b(2019) Standard Test Method for API Gravity of Crude Petroleum and result in a subsequent calculation procedure (measurement ticket calculation, 6 Dec 2013 Keywords: Crude oil; API number; Ultrasound velocity; Equation of state. Introduction. Crude oil is of the mixture of crude oils having different API gravity. This helps us It can be utilized for calculation of the thermodynamic 4 Jun 2015 Any calculation involving the movement of fluids requires a value of Viscosity increases with decreases in crude oil API gravity (assuming a
If you have the crude density given in °API, use the API-to-gravity converter. See also similar correlations for lubricating oil , fuel oils and jet fuel . Volume correction factors can be used to calculate the volume of a crude at base temperature (15°C/59°F) if you know the density and volume at another temperature.
