WebThe bulk density, then, is the dry weight of soil divided by the volume of soil: 1.33 g / 1 cm 3 = 1.33 g/cm 3 For practice, consider a box of undisturbed soil from the field. The box has dimensions of 2.5 cm by 10 cm by 10 cm. The volume of the box can be determined by multiplying the height of the box times its width and its depth. WebSometimes, we use wet bulk density, and it is defined as r wb = (m l + m s)/V Moreover, we define density of each of the specific phases, or r m = m s/V s varies between 2.6-2.65 …
