Which principle is applied in the working of Lactometer?

Archimede’s Principle
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.

What is the application of Archimedes Principle?

Archimedes’ principle is very useful for calculating the volume of an object that does not have a regular shape. The oddly shaped object can be submerged, and the volume of the fluid displaced is equal to the volume of the object. It can also be used in calculating the density or specific gravity of an object.

Which instrument is based on principle of Archimedes?

Lactometer
Lactometer is based on the principle of Archimedes. Archimedes’ principle, states that any body completely or partially submerged in a fluid (gas or liquid) at rest is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid displaced by the body.

What is the uses of Lactometer?

A Milk Hydrometer also known as a lactometer is an instrument that is used to check for the purity of milk by measuring its density.

What do you know about Archimedes Principle?

Archimedes’ principle states that a body immersed in a fluid is subjected to an upwards force equal to the weight of the displaced fluid. This is a first condition of equilibrium. We consider that the above force, called force of buoyancy, is located in the centre of the submerged hull that we call centre of buoyancy.

Is submarine based on Archimedes Principle?

The submarine operates using the Archimedes’ principle by manipulating the buoyancy. The buoyancy is controlled by the ballast tank system. the submarine can obtain neutral buoyancy. That means the weight of the submarine equals the amount of water it displaces.

What are fluids Why is Archimedes principle applicable only for fluids give the application of Archimedes Principle?

Archimedes principle is applicable only for fluids because: Only fluids exert buoyant force. An object cannot be immersed in a solid, but it can be immersed in a fluid.

How is Archimedes Principle used to design submarines?

Archimedes principle is used to design Submarines. Archimedes principle – It states that anybody who is completely or partially submerged in a fluid at rest is acted upon by an upward buoyant, force. At this stage, the submarine ballast tanks are filled with seawater which is denser than the surrounding water.

Which instrument is not working based on the Archimedes principle?

Hydrometer – From this, the specific density of the liquids is extracted and their purity is tested. Lactometer – It is an Instrument used for finding the purity of a milk sample. Odometer – It is an instrument for measuring the distance by a wheeled vehicle. It doesn’t depend on the Archimedes principle.

What are the two instrument based on Archimedes principle?

Answer: lactometer And hydrometer are based on Archimedes’ principle.

What are the 2 types of Lactometer available?

The quevenne lactometer – designed to determine the specific gravity of milk at 15.5ºC (60ºF). Zeal Lactometer – designed to determine the specific gravity of milk at 29º C at 84º C. The Watson lactometer – is applied at a temperature of 39ºC. ISI lactometer calibrated at 27ºC is used.

How Archimedes Principle is used to design ships and submarines?

Archimedes’ principle is also used in designing ships and submarines. The weight of the water displaced by the ship is much more than its own weight. This makes the ship float on water. A submarine can dive into the water or rise to the surface as needed.

How does the Archimede’s test work?

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. If it is not, then there is some adulteration.

What is a lactometer and how does it work?

What is Lactometer? 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.

How can the Archimedes principle be used to determine the density?

How can the Archimedes Principle be used to determine the density? The weight of the fluid displaced is equal to the buoyant force on a submerged object. The mass divided by the volume thus determined gives a measure of the average density of the object. Stay tuned with BYJU’S to learn more interesting topics with engaging videos!

What is Archimedes’ principle equation?

Archimedes’ Principle Equation Archimedes’ principle tells us that this loss of weight is equal to the weight of the fluid, wholly or partially, displaced by the object. The corresponding equation is given by, Fb = ρ X g X V
