Q1:

Buoyant unit weight equals the saturated density

A multiplied by unit weight of water

B divided by unit weight of water

C plus unit weight of water

D minus unit weight of water.

ANS:D - minus unit weight of water.

Buoyant unit weight is another name of submerged unit weight;

In general, submerged unit weight = sat. unit weight-unit weight of water. Saturated unit weight = submerged unit weight + unit weight of water. Buoyant weight = unit weight of submerged - unit weight of water.
