Learn how to calculate specific gravity and its significance in material science and engineering.

119 views

The formula for calculating specific gravity is the ratio of the density of a substance to the density of a reference substance, typically water. The formula is: Specific Gravity (SG) = Density of the Substance / Density of Water. This dimensionless number indicates whether a substance will float or sink in water, and it's crucial in fields like material science and engineering.

FAQs & Answers

  1. What is specific gravity used for? Specific gravity is used to determine whether a substance will float or sink in water and is vital in various industries such as engineering and material science.
  2. How is specific gravity measured? Specific gravity is measured by comparing the density of a substance to the density of a reference substance, usually water.
  3. What are some common applications of specific gravity? Specific gravity is commonly applied in material selection, buoyancy calculations, and quality control in manufacturing processes.
  4. Can specific gravity be greater than 1? Yes, substances with a specific gravity greater than 1 will sink in water, while those with a specific gravity less than 1 will float.
