− | Buoyancy is the tendency for a body (or a drop of immiscible fluid) to float or rise when submerged in a fluid of greater density. Where two immiscible fluids (oil and water) occur together, they create a buoyancy pressure that is a function of the density difference between the two fluids and the length of the less-dense fluid column. | + | Buoyancy is the tendency for a body (or a drop of immiscible fluid) to float or rise when submerged in a fluid of greater [[density]].
