Buoyancy

The resultant force acting on a submerged body by the fluid is called the buoyant force and can be expressed as

F = V γ

    = V ρ g        (1)

where

F = buoyant force (N)

V = body volume (m³)

γ = specific weight of fluid (N/m³)

γ = specific weight of fluid (N/m³)

ρ = density of fluid (kg/m³)

g = acceleration of gravity (= 9.81 m/s²)

The buoyant force acts upwards.
