The flow net constructed for the dam is shown in the figure below. Taking the coefficient of permeability as 3.8 × 10–6 m/s, the quantity of flow (in cm3 /s) under the dam per meter of dam is __________.
-
- 7.182 cm3 /s/m
- 7.005 cm2 /s/m
- 7.958 cm4 /s/m
- 6 cm3 /s/m
Correct Option: A
7.1 to 7.85
No. of flow channels, Nf = 3
No. of equipotential lines, Nd = 10
K = 3.8 × 10–6 m/s
H = 6.3 m
| = 3.8 × 10–6 × 6.3 × | 10 |
= 7.182 × 10–6 m3 /s/m
= 7.182 cm3 /s/m
