A Closer Look At The Concept Of Specific Gravity

By:


Known as an interesting concept concerning relative density, specific gravity focuses on a substances density that is equated with the water density at four degrees Fahrenheit. Specific gravity has a similar density with water, however, it does not have any unit. The relations between specific gravity and relative density are essential to determine if a particular substance will sink in water.

Overview

Learning the concept is significant to identify its applications in various fields and industries. In this regard, it is best to start with determining specific gravity in gases, solids and liquids. When identifying this concept in liquids, it is important to use a hydrometer. Remember that the point where the device sinks is inversely related to the liquid's gravity.

On the other hand, electronic scales can be used to examine the SG of solids. They are helpful in determining the purity of gems. Moreover, the SG of gases can be assessed with the use of transducers, which are helpful for the gas, oil, process and aerospace industries.

Practical Applications

One of the most popular applications of SG is in the metal industry because it is helpful in identifying the impact of the speed of sound on metals. Aside from this use, it is also useful in the poultry industry. With this concept, it is easy for the owners and workers in the industry to determine the thickness of an eggshell. In addition, having a sufficient background on specific gravity is applicable in knowing the compressive strengths of soils. Finally, in the oil industry, such concept is important to know the measurement of refined products and crude oil.

Additional Information and Other Important Details

The concept is applicable in the oil industry because it is used to determine the types of oil. For instance, the ranges of SG in crude oils are between 0.80 to 0.97 while in aviation gasoline, it ranges around 0.70 to 0.78. When it comes to diesel oils, their specific gravity is between 0.82 to 0.92 while the gravity for lubricating oils is between 0.85 to 0.95. Lastly, oil producers should know that the specific gravity of asphaltic bitumens is around 1.00 to 1.10.
