From this equation we see that there is a limiting dry unit weight for any moisture content and this occurs when the voids are full of water Increasing the water content for a saturated soil results in a reduction in dry unit weight The relation between the moisture content and dry unit weight for saturated soil is shown on the graph in Figure 3...
