Void ratio (e) is the ratio of the volume of void space to the volume of solids. The void ratio is usually expressed as a decimal quantity[1].


The following equation can be used to determine the void ratio of a soil or solid bulk cargo:



e = void ratio,
Vv = volume of voids,
Vs = volume of solids,
ρst = specific gravity or particle density (t/m3 or g/cm3),
ρd = dry density (t/m3 or g/cm3),
w = net water content by weight (%) and
S = degree of saturation.
