The specific gravity of a fluid may be measured

Last updated: 7/26/2022

The specific gravity of a fluid may be measured experimentally using an instrument called a Hydrometer. You may have already used a hydrometer to check the consistency of your car's battery fluid or the amount of sediment in wine. In medical fields, the fluid most commonly tested is urine. The Hydrometer used to test the specific gravity of urine is called a Urinometer. Urine is a fluid used to remove harmful wastes from the body. These wastes are dissolved in water, which gives urine a higher density than water alone. The normal density of urine is between 1.003 g/mL and 1.030 g/mL. What is the normal range of the specific gravity of urine? (Assume that the density of water is 1 g/mL)
