engineering recuitment FCI JE 2022 Mock Test for CE/ME/EE (Phase I & II) Soil Mechanics and Foundation Engineering Permeability
A stratified soil deposit consists of three layers. The permeabilities of the layers are 8 x 10-4, 50 x 10-4 and 15 x 10-4 cm/sec; the thickness of the layers are 6 m, 3 m and 12 m respectively. Then the average permeability of the deposit parallel to plane is:
1
1.4 x 10-3 cm/sec
2
1.34 x 10-3 cm/sec
3
2.0 x 10-3 cm/sec
4
1.5 x 10-3 cm/sec
5
1.8 x 10-3 cm/sec
