Procedure to define the Specific Gravity
Briefly explain the procedure to define the Specific Gravity?
Expert
The Specific Gravity, SG, is the unit less quantity which provides the scientist or engineers an idea of how dense a substance is as compared to water. The density of water that is one kilogram per liter (at 4 oC), is assigned a SG of about 1.000. When a substance is denser than water, it will contain a SG greater than 1.000; whenever it is less dense than water, its SG will be a value less than 1.000 (however greater than zero). Let's state a substance consists of a density of 2.5 kilograms per liter. That signifies that its SG is 2.5 (that is, 2.5 divided by 1.000).
