Hydrometers are based on Archimedes' principle because they work by measuring the displacements of liquid when immersed. According to Archimedes' principle, the buoyant force acting on an object in a fluid is equal to the weight of the fluid displaced by the object. By measuring the amount of liquid displaced by the hydrometer, its density and hence specific gravity can be determined.
The principle of specific gravity, based on Archimedes' principle, is used in various industries to determine the purity or concentration of substances. For example, in the pharmaceutical industry, it is used to measure the concentration of active ingredients in solutions. In the field of materials science, it is used to assess the density and quality of materials like metals and polymers.
Buoyant force is the upward force exerted by a fluid on an object placed in it, and Archimedes' principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. By applying Archimedes' principle, we can determine whether an object will float or sink in a fluid based on its density compared to the fluid.
Archimedes is credited with discovering the principle of buoyancy, known as Archimedes' principle. This principle states that the upward buoyant force on an object immersed in a fluid is equal to the weight of the fluid that the object displaces.
Archimedes' principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. This principle helps determine whether an object will float or sink in a fluid based on its density compared to the density of the fluid.
The greatest buoyant force an object can experience in water is determined by the weight of the water displaced by the object. According to Archimedes' principle, the buoyant force is equal to the weight of the fluid displaced by the object.
