For a homogeneous earth dam 50 m high having 2 m free broad, a flow net was constructed and
the results were : Number of potential drops = 2.4 Number of flow channels = 0.4. If co-efficiency
of permeability of the dam material is 3 × 10-3 cm3
/sec, the discharge per metre length of dam, is
(A) 12 × 10-5 m3
/sec
(B) 24 × 10-3 m3
/sec
(C) 6 × 10-5 m3
/sec
(D) 24 × 10-5 m3
