Calculate the voide ratio if the hydraulic gradient 1.2 and specific gravity of soil is 1.89 .
Answers
The void ratio of the soil with hydraulic gradient 1.2 and specific gravity 1.89 is - 0.25833 ( no unit ) ( negative indicates that the density of the soil is affected when there is increase in load )
Explanation:
- Void ratio is defined as the ratio of volume of voids and volume of solids
- Void ratio is a dimensionless quantity and it is somewhat related to porosity also
- Hydraulic gradient is a type of driving force
- Specific Gravity of soil is defined as the ratio of unit weight of the soil mass and unit weight of distilled water at 4°C. Also it is compared to the density of the soil to the density of the distilled water in some cases.
Given Data
Hydraulic gradient of soil = 1.2
Specific gravity of soil = 1.89
To find - the Void ratio of the soil
The formula to find the hydraulic gradient of the soil by using Specific gravity and void ratio is
Hydraulic gradient = (G-1) ÷ ( 1+e) ----------> 1
Where G = Specific gravity of the soil
and e = Void ratio of the soil
The above formula (1) of hydraulic gradient cal be rewritten as
( 1+e ) = ( G-1) ÷ Hydraulic gradient ----------> 2
Substitute the given values in equation 2
( 1+e ) = (1.89 - 1) ÷ 1.2
( 1+e ) = (0.89 ) ÷ ( 1.2 )
( 1+e ) = 0.74166
e = 0.74166 - 1
e = -0.25833 ( no unit)
Therefore the void ratio of the soil is - 0.25833 ( no unit )
