Bulk Materials - Buoyancy

Archimedes Principle

When body immersed in fluid, fluid exerts an upward force equal to weight of fluid displaced. (by the body)

Fbuoy = Weight of displaced fluid

= pfluid x Vdisp x g

p = density of fluid

=m/V

When body at rest in equilibrium, total weight of body = Fbuoyant

therefore mg = pfVg

Apparent Weight = Actual Weight - Buoyant Force
