where is lactometers used? 80 words​

Answer 1

The hydrometer (or lactometer) is based on Archimedes' principle, which states that a solid suspended in a fluid is buoyed by a force equal to the weight of the fluid displaced by the submerged part of the suspended solid. Hence, the lower the density of the substance, the farther the hydrometer sinks..

Answer 2

Answer:

• Operation of the hydrometer is based on Archimedes' principle that a solid suspended in a fluid will be buoyed up by a force equal to the weight of the fluid displaced. Thus, the lower the density of the substance, the farther the hydrometer will sink. They both work on Archimedes principle. Using this, they are used to calculate the density of milk (lactometer) and other substances. The hydrometer (or lactometer) is based on Archimedes' principle, which states that a solid suspended in a fluid is buoyed by a force equal to the weight of the fluid displaced by the submerged part of the suspended solid. Hence, the lower the density of the substance, the farther the hydrometer sinks. An instrument to find out the content of the water in the milk or to test the richness of the milk is thus termed as 'lactometers'. The lactometer works on the principle of gravity of milk. A Lactometer measures the cream content of milk. The more cream, the lower the lactometer floats in the milk.

• Lactometer is a small glass instrument that is used to test the purity of the milk. It works on the principle of specific gravity of milk (Archimede's Principle). It measures the relative density of milk with respect to water. If the specific gravity of a sample of milk is within the approved ranges, the milk is pure.
