2.2.1 Grain Packing The theoretical porosities for various grain packing arrangements can be calculated. The theoretical maximum porosity for a cubic packed rock made of spherical grains of a uniform size is 0.4764, and is independent of grain size. The maximum porosity of other packing arrangements is shown in Table 2.1 and Figure 2.1.

How to Calculate Void Ratio - ProjectEngineer
Dec 16, 2013· The void ratio is the ratio of the volume of voids (open spaces, i.e. air and water) in a soil to volume of solids.. Where: e = Void Ratio V v = Volume of voids (m 3 or ft 3) V s = Volume of solids (m 3 or ft 3) V g = Volume of air (m 3 or ft 3) V w = Volume of water (m 3 or ft 3) The void ratio is thus a ratio which can be greater than 1. It can also be expressed as a fraction.
