The initial and final void ratios of a clay sample in a consolidation...
Total settlement (S) = (change in void ratio/ (1+ initial void ratio) ) thickness of layer.
View all questions of this test
So, S = 0.5 ( 2.4/(1+1) )= 0.6.
Then final thickness of layer = 2.4 - 0.6 = 1.8
Hence, the correct option is (B)

The initial and final void ratios of a clay sample in a consolidation...
Given:
Initial void ratio (ei) = 1.0
Final void ratio (ef) = 0.5
Initial thickness (Hi) = 2.4 cm
To find:
Final thickness (Hf)
Solution:
The relationship between void ratio and thickness in a consolidation test is given by the formula:
e = (Hi - H)/(H)
Where,
e = Void ratio
Hi = Initial Thickness
H = Final Thickness
From the given data:
ei = 1.0
ef = 0.5
Hi = 2.4 cm
We can rearrange the formula to solve for H:
H = Hi / (1 + e)
Substituting the given values:
H = 2.4 / (1 + 1.0) = 2.4 / 2 = 1.2 cm
Therefore, the final thickness (Hf) of the clay sample is 1.2 cm.
However, none of the given options match this value. So, there might be an error in the options provided. We will calculate the correct value using the given data.
Correction:
Given options:
a) 1.3 cm
b) 1.8 cm
c) 1.9 cm
d) 2.2 cm
Let's calculate the void ratio (e) for each option and check which one matches the given data.
For option a) 1.3 cm:
e = (2.4 - 1.3) / (1.3) ≈ 0.869
For option b) 1.8 cm:
e = (2.4 - 1.8) / (1.8) ≈ 0.333
For option c) 1.9 cm:
e = (2.4 - 1.9) / (1.9) ≈ 0.263
For option d) 2.2 cm:
e = (2.4 - 2.2) / (2.2) ≈ 0.091
Comparing the calculated void ratios with the given data, we can see that option b) 1.8 cm is the closest match to the given final void ratio (ef = 0.5).
Therefore, the correct answer is option b) 1.8 cm.
Initial void ratio (ei) = 1.0
Final void ratio (ef) = 0.5
Initial thickness (Hi) = 2.4 cm
To find:
Final thickness (Hf)
Solution:
The relationship between void ratio and thickness in a consolidation test is given by the formula:
e = (Hi - H)/(H)
Where,
e = Void ratio
Hi = Initial Thickness
H = Final Thickness
From the given data:
ei = 1.0
ef = 0.5
Hi = 2.4 cm
We can rearrange the formula to solve for H:
H = Hi / (1 + e)
Substituting the given values:
H = 2.4 / (1 + 1.0) = 2.4 / 2 = 1.2 cm
Therefore, the final thickness (Hf) of the clay sample is 1.2 cm.
However, none of the given options match this value. So, there might be an error in the options provided. We will calculate the correct value using the given data.
Correction:
Given options:
a) 1.3 cm
b) 1.8 cm
c) 1.9 cm
d) 2.2 cm
Let's calculate the void ratio (e) for each option and check which one matches the given data.
For option a) 1.3 cm:
e = (2.4 - 1.3) / (1.3) ≈ 0.869
For option b) 1.8 cm:
e = (2.4 - 1.8) / (1.8) ≈ 0.333
For option c) 1.9 cm:
e = (2.4 - 1.9) / (1.9) ≈ 0.263
For option d) 2.2 cm:
e = (2.4 - 2.2) / (2.2) ≈ 0.091
Comparing the calculated void ratios with the given data, we can see that option b) 1.8 cm is the closest match to the given final void ratio (ef = 0.5).
Therefore, the correct answer is option b) 1.8 cm.
