91) State the following statement correct or false.
Statement : The value of the degree of saturation in a fully dry soil sample is zero.
- a) True
- b) False
Answer: a) True
The value of the degree of saturation in a fully dried soil sample is zero since the value of water volume is equal to zero.
The formula of the degree of saturation:
S = Vw/Vv …(i)
Vw = Volume of water
Vv = Volume of void
In the case of the fully dried soil sample, the volume of water is zero.
i.e. Vw = 0…(ii)
From equation (i) & (ii) , we will get,
S = 0/Vv
Hence, the value of the degree of saturation is zero in a fully dried soil sample.
