The two forces acting on the fluids in the pore space are controlled by physical laws. The equation for the buoyancy pressure is given by
The two forces acting on the fluids in the pore space are controlled by physical laws. The equation for the buoyancy pressure is given by
:<math>P_b = (\rho_w - \rho_{nw})gh</math>
where Pb is the buoyancy pressure; ρw and ρnw are the specific gravities of the wetting and nonwetting phases respectively; g is the acceleration of gravity; and h is the height above the free-water level.
