Question: Assuming a two - phase solid - water system, derive a formula for the saturated unit weight in terms of the porosity ( n )

Assuming a two-phase solid-water system, derive a formula for the saturated unit weight in terms of the porosity (n), the specific gravity of solids (Gs), and the unit weight of water. Use a block diagram for the derivation. Determine the saturated unit weight (pcf) for a sand with a 35% porosity and Gs =2.67.
