Definition

A physical principle stating that a body wholly or partially immersed in a fluid at rest experiences an upward buoyant force equal in magnitude to the weight of the fluid displaced by that body.

Definition

A body wholly or partly submerged in a fluid at rest experiences an upward buoyant force whose magnitude equals the weight of the fluid displaced by the submerged portion; the resultant buoyant force acts through the center of buoyancy (the centroid of the displaced volume).

Definition

The upward buoyant force on a body wholly or partially immersed in a fluid equals the weight of the fluid that the body displaces; quantitatively, the buoyant force B = ρ_f·V_disp·g, where ρ_f is fluid density, V_disp the volume of displaced fluid and g gravitational acceleration.
