Learn unit weight of soil, bulk unit weight, dry unit weight, unit weight of solids, unit weight Unit weight of soil The unit weight of a soil mass is defined as its weight per unit volume. Bulk unit weight. The bulk weight or moist unit weight is the total weight W of a soil mass per unit of its total volume V. \[\gamma = \frac{W}{V}\] Dry unit weight. The dry unit weight is the weight of solids per unit of its total volume (prior to drying) of the soil mass: \[\gamma_{d} = \frac{W}{V_{d}}\] Unit weight of solids. The unit weight of soil solids is the weight of soil solids Wd per unit volume of solids (Vs): \[\gamma_{s} = \frac{W_{d}}{V_{s}} \] Thus, when the dry weight is reckoned with reference to the total original volume V, it is called the dry unit weight and when it is reckoned with reference to…
