Archimedes’ principle

It states that ” The buoyancy force (or upward force) exerted on a body immersed in a fluid (liquid or gas) is equal to the weight of the fluid displaced by the body.”

Mathematically:

Fb = ρVg

Where:

Fb = Buoyancy force (N)

ρ = Density of fluid (kg/m³)

V = Volume of fluid displaced (m³)

g = Acceleration due to gravity (m/s²)

Applications :-

1. Ship design : Calculating buoyancy and stability
2. Offshore platforms : Ensuring structural integrity.
3. Submarines: Controlling depth buoyancy.
4. Flotation devices: Life jackets, flotation bags.
5. hydroelectric power: Measuring water pressure.
6. lactometers: which are used to determine the purity of a sample of milk.
