What is the formula for calculating buoyancy?

Buoyancy refers to the force that an object immersed in a fluid is vertically lifted by the fluid. The definition formula of buoyancy is F float =G row, and the calculation formula is: F float = gV row of ρ liquid, where ρ liquid represents the density of liquid in kg/m3; G represents a constant, g = 9.8n/kg；; Line V represents the volume of discharged liquid in cubic meters.

Cause of buoyancy

An object immersed in liquid, such as a cube, has its left, right and front sides at the same depth, and the pressures are balanced with each other. Because the depths of the upper and lower bottom surfaces are different and the pressures are different, the lower pressure is greater than the upper pressure, so that the upward pressure on the object is greater than the downward pressure, and the difference between these two pressures forms the buoyancy of the liquid on the object.
