Question

The relationship between coefficient of permeability and coefficient of percolation is ______

(a) kp=kn

(b) kp=ke

(c) kp=k/e

(d) kp=k/n

This question was addressed to me in quiz.

My question is taken from Permeability topic in division Permeability of Geotechnical Engineering I

Answer 1

Right option is (d) kp=k/n

For explanation I would say: From Darcy’s law, V=ki

And Vs=kpi

∴ Vs/V=kp/k=1/n

∴ kp=k/n.
