How to calculate and measure specific gravity. If the density of a substance is known, to calculate the specific gravity of a substance simply divide the density of the substance by the density of water or air. Because the density of water is 1000 kg/m3 or 1 g/cm3, it is simple to calculate.
How to Find the Specific Gravity?
Specific gravity is an important concept when it comes to working with liquids, gas, and solids. It is a measure of the density of a material, which is the ratio of the density of a material to the density of water. Knowing the density of a material is important for many applications, such as understanding the behavior of different liquids. Finding the specific gravity of a material can help you determine the amount of energy it takes to move a certain amount of material, or the amount of material needed to fill a container.
The most accurate method of determining the specific gravity of a material is to use a hydrometer. A hydrometer is a device that measures the density of a liquid or solid by comparing it to the density of a reference liquid. It consists of a glass or plastic tube with a weighted bulb at the bottom and a scale. When the hydrometer is placed in a liquid, the bulb sinks until it reaches a point where the density of the liquid is equal to that of the reference liquid. The hydrometer then reads the specific gravity of the liquid.
For those who don’t have access to a hydrometer, there are other methods of finding the specific gravity of a material. One way is to use a container
