What is API Gravity? Petro Online

API gravity classifications and grades. In general oils with API gravity of 40 – 45 generate the highest market prices. Any oils with API gravity of 45 or over have shorter molecular chains which are less desirable to refineries. Below is an overview of the four major crude oil classifications: Light crude oil; Any crude oil with API gravity ...

Density & Specific Gravity - Meteorite Information

Specific gravity is the ratio of the mass (weight) of a rock to the mass of the same volume of water. Water has a density of 1.0 g/cm 3, so the numeric value of specific gravity for a rock is the same as that for density. Because specific gravity is a ratio, it has no unit. Specific gravity is easier to measure than density.

Difference Between Density and Specific Gravity

Apr 23, 2018 · Both density and specific gravity describe mass and may be used to compare different substances. They are not, however, identical measures. Specific gravity is an expression of density in relation to the density of a standard or reference (usually water).

The Basics of Crude Oil Classification

Crude can be classified as "light" or "heavy," a characteristic which refers to the oil's relative density based on the American Petroleum Institute (API) Gravity. This measurement reflects how light or heavy a crude oil is compared to water. If an oil's API Gravity is greater than 10, .

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal, drag or buoyant forces). The resistance to motion, known as drag force, by a medium such as heavy media, water or even air, is one such force.

For example, with a hydrometer reading of 1.052, the numbers to the right of the decimal (52) are the gravity units (GU). Read simply, the density of the wort is 5.2 percent higher than that of water. As yeast works to consume the sugar, the density of the wort is decreased, which causes the hydrometer to deliver a reading closer to 1.000.
