1.6 = (1*2.56)/(1+e);
e = 0.6;
n = e/1+e;
n = 0.6/(1+0.6);
Then n = 0.375.

rd=1.6g/cc ,r=1.84g/cc relation is rd=r/1+w.
We get water content w= 0.15.

Instead of 1.84 take the standard value of density of water that is 1g/cc.

Biki said:   7 years ago
The water density is given as 1.84 g/cc , then how the answer is 375?

Sudarsan Sahoo said:   9 years ago
Then what about the value of water density or what does that signify?

Bhakt said:   9 years ago
Both are right @Rubby and @Reddy.

The void ratio is (e).

VINOD said:   5 years ago
If we take water density 1.84 then porosity will be 0.66.

I think it should be the wet density of the soil sample.

Ravi said:   5 years ago
If water density is considered the answer must be .66.

Abhik said:   7 years ago
By using the density of water the answer is 0.66.
