How is specific gravity measured?

Answer 1

Specific gravity is the ratio of the density of a substance to the density of a reference substance, typically water for liquids and solids, and air for gases. Specific gravity can be measured using a hydrometer, which is a device that consists of a weighted glass or plastic tube that floats in the liquid. The hydrometer has a graduated scale that is used to read the specific gravity of the liquid. Another method is to use a digital density meter, which uses electronic sensors to measure the density of the substance. In this method, the substance is placed in a container and the electronic sensors measure the weight and volume of the substance to calculate its density and specific gravity.

Answer 2

specific gravity is measured using a hydrometer, which is a device that consists of a weighted glass or plastic float inside a cylindrical tube. the hyrdometer is placed in a liquid, and the float rises or falls depending on the density of the liquid. The specific gravity of the liquid can then be determined by reading the scale on the hydrometer. another way to measure specific gravity is through a digital specific gravity meter, which is using electronic sensor to measure the weight of the liquid and the weight of equal volume of water.

Answer 3

(Relative density) Density of liquid, compared to water.

>

Water density = 1 gram / cubic centimetre.

>

Say sample density = 1.25 gram / cubic centimetre

>

Relative density = 1.25 / 1 = 1.25

Answer 4

It is found by using geometry and other scienific, complex mathematics.
