Relation Between Void Ratio, Water Content, Degree of Saturation & Specific Gravity
In this article, we will make a formula or equation or relation between void ratio(e), water content(w), degree of saturation() and specific gravity(G).
Let,
= Weight of soil solid in a given soil mass.
= Weight of water.
= Volume of soil solid in a given soil mass.
= Volume of water present in the given soil mass.
= Unit weight of soil solids or density of solids.
= Unit weight of water or density of water.
By definition of water content, we can write,
Or,
[ We know, ]
Or,
Or,
[ We know, and
]
So,
Or,
Alternative Method,
By the definition of void ratio, we have,
Or,
Or,
Or,
Or,
Or,
