Void ratio (e):
Void ratio (e) is the ratio of the volume of voids (Vv) to the volume of soil solids (Vs), and is expressed as a decimal.
e = Vv/Vs
Porosity (n):
Porosity (n) is the ratio of the volume of voids to the total volume of soil (V), and is expressed as a percentage.
n = (Vv/V) × 100
Relation between void ratio and porosity
n = e/(1+e)
Calculation:
Given,
Vv = Vs
∴ e = Vv/Vs
e = Vv/Vv = 1
∵ n = e/(1 + e)
n = 1/(1 + 1) = 1/2 = 0.5
