Question

A stratum of soil consists of three layers
of equal thickness. The permeabilities of
top and bottom layers are K = 10-4 cm/s
and that of the middle layer is K = 10-3
cm/s. Then the value of the horizontal
coefficient of permeability Kh for the
entire soil layers is
a) 2 x 10 cm/s
b) 4 x 10-4 cm/s
c) 3 x 104 cm/s
d) 1.5 x 104 cm/s​
