Get PriceThe void ratio is thus a ratio which can be greater than 1. It can also be expressed as a fraction. It can also be expressed as a fraction. Void ratio and porosity differ only in the denominator.

Get PricePorosity is the percentage of void space in a rock. It is defined as the ratio of the volume of the voids or pore space divided by the total volume.

Get PriceA related quantity is the porosity, n, which is defined as ratio of the volume of voids to the total volume. n V V = v The relation between e and n can be determined by noting that Vs = V Vv = (1 n) V Now e V V V nV n n v s ==v âˆ’ = ()11âˆ’ and hence n e e = 1 + Degree of Saturation The degree of saturation, S, has an important influence on the soil behaviour. It is defined as the ...
