Question

Coefficient of absolute permeability (K) depends on ____________

(a) Permeant

(b) Properties of soil mass

(c) Degree of saturation

(d) All of the mentioned

I have been asked this question in a job interview.

Origin of the question is Determination of Coefficient of Permeability in chapter Permeability of Geotechnical Engineering I

Answer 1

Right option is (b) Properties of soil mass

Explanation: From the equation of coefficient of absolute permeability,

K = C (e3/1+e) D3

We can find that coefficient of permeability is independent of the properties of permeant (i.e. water) and it depends solely on the properties of soil mass.
