Crude oil is classified as light, medium, or heavy according to its measured API gravity. Light crude oil has an API gravity higher than 31.1° (i.e., less than 870 kg/m 3) Medium oil has an API gravity between 22.3 and 31.1° (i.e., 870 to 920 kg/m 3) Heavy crude oil has an API gravity below 22.3° (i.e., 920 to 1000 kg/m 3 Specific gravity is especially important for the petroleum industry. When crude oil is taken from the ground, refineries separate the crude into tar, kerosene, gasoline, hydraulic oil and many other compounds. The knowledge of specific gravities and boiling points allows refineries to separate these compounds efficiently Oils Oils vary in their specific gravity, so it is possible to 'float' one oil on top of the other simply because of the difference in their SG. Pictured is an example of castor oil and apricot kernel oil. SG of Castor oil: 0.96 SG of Apricot kernel oil: 0.90 - 0.9

Sweet Almond has a specific gravity of .92 which means 1 fluid ounce weighs .92 ounce. When you purchase, or use, a product and the label says 16 oz, by law, it. Specific gravity is calculated as the ratio of the density of a liquid to the density of water. So any liquid with a density greater than water has a specific gravity greater than 1. Liquids with a density lower than water, which includes most crude oil grades and petroleum products, will have a specific gravity between 0.0 and 1.0 Relative density, or specific gravity, is the ratio of the density of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest; for gases, the reference is air at room temperature. The term relative density is often preferred in scientific usage. If a substance's relative density is less than 1 then it is less dense than the reference; if greater than 1 then it is denser than the reference. If the rel API Gravity.

Moreover, in thi9s topic we will discuss specific gravity, specific gravity formula and its derivation and solved examples Specific gravity, also referred to as relative density, is used to relate the weight or density of liquids to that of water. Specific gravity is a unitless measurement that is derived as a ratio of either the weight of another liquid or the density of another liquid divided by the weight or density of water When using oils, Buna or NBR floats are best. These floats have low specific gravity, around .5, and will float well in most petroleum products ranging from .7 to .86 SG. For example, a float switch with a specific gravity of .8 will float well in water but will sink in alcohol which is around .72 SG. Below is a table liquid for reference Calculating 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.

Specific gravity is important when sizing a centrifugal pump because it is indicative of the weight of the fluid, and its weight will have a direct effect on the amount of work performed by the pump. One of the beauties of the centrifugal pump is that the head (in feet) and flow it produces has nothing to do with the weight of the liquid Specific Gravity Equation. The specific gravity of oil is the ratio between its density and the density of water. You can calculate specific gravity with this simple equation: Density of the fluid ÷ Density of water = Specific Gravity. Water always has a density of approximately 1,000 kilograms per cubic meter.
