A short note on the buoyant force in nonuniform gravitational fields

Classical Physics 2025-08-05 v1 Fluid Dynamics

Abstract

Lima and Monteiro [1] derived the buoyant force in a nonuniform gravitational field by applying a gradient version of the divergence theorem to the surface integral of the pressure forces [2]. Here it is outlined an alternate approach in the framework of fluid mechanics, based on the energy formulations of the equations of state for compressible fluids.
