Submerged Unit Weight Formula

Equation for calculate submerged unit weight is,

$γ' = γ_{s} - γ_{w}$

where,

γ_s is the saturated unit weight of the material
γ_w is the unit weight of water
γ′ is the submerged unit weight of the material

γ_s is the saturated unit weight of the material

γ_w is the unit weight of water

γ′ is the submerged unit weight of the material
