Specific Gravity:
(i) Specific Gravity of soil solids (G) is the ratio of the weight of a given volume of solids to the weight of an equivalent volume of water at 4°C
Specific Gravity = Mass density of liquid/Mass density of water
\(0.7= {Specific\ weight\ of\ material\over Specific\ weight\ of\ water}\)
\(0.7= {γ\over 9.81}\)
γ = 9.81 × 0.7 = 6.867 kN/m3 = 6867 N/m3
Important Points
Specific Volume:
(i) Specific volume is defined as the number of cubic meters occupied by one kilogram of matter. It is the ratio of a material's volume to its mass, which is the same as the reciprocal of its density.
Density:
(i) density is defined as mass per unit volume.
Unit weight:
(i) Unit weight is defined as total weight per unit volume.
