Question

If the coefficient of permeability of soil is 9*10^-7cm/s and porosity is 0.33, then its coefficient of percolation is ______

(a) 8*10^-7cm/s

(b) 27*10^-7cm/s

(c) 26*10^-7cm/s

(d) 13*10^-7cm/s

I had been asked this question by my school principal while I was bunking the class.

I would like to ask this question from Permeability topic in section Permeability of Geotechnical Engineering I

Answer 1

The correct option is (b) 27*10^-7cm/s

For explanation: Given,

coefficient of permeability k=9*10^-7cm/s

porosity n=0.33

coefficient of percolation kp=k/n=(9*10^-7)/0.33

∴ kp=27*10^-7cm/s.
