Given:
- Flow channels: 6
- Equipotential drops: 18
- Head of water lost during seepage: 6 m
- Coefficient of permeability of foundation: 4 x 10-5 m/min
To find: Seepage loss per meter length of dam
Formula:
Seepage loss (Q) = k * A * i
Where,
Q = Seepage loss
k = Coefficient of permeability
A = Cross-sectional area of flow channels
i = Hydraulic gradient
Step 1: Find the cross-sectional area of flow channels (A)
Since there are 6 flow channels, we need to divide the total area of the flownet by 6 to get the cross-sectional area of each flow channel.
Step 2: Find the hydraulic gradient (i)
The hydraulic gradient can be calculated using the formula:
i = h/L
Where,
h = Head of water lost during seepage
L = Total length of flownet
Step 3: Calculate the seepage loss (Q)
Using the formula mentioned above, we can calculate the seepage loss per meter length of dam.
Calculations:
Step 1:
Let's assume the total area of the flownet is A_total.
Cross-sectional area of each flow channel (A) = A_total / 6
Step 2:
Given that the head of water lost during seepage (h) = 6 m
The total length of the flownet (L) can be calculated by multiplying the number of equipotential drops (n) by the spacing between them (d).
L = n * d
Step 3:
Using the values of A, k, and i, we can calculate the seepage loss (Q).
Finally, divide Q by the length of the dam to get the seepage loss per meter length of dam.
Answer:
The seepage loss per meter length of dam is option 'c' (11.52 x 10-2 m3/day).
- Flow channels: 6
- Equipotential drops: 18
- Head of water lost during seepage: 6 m
- Coefficient of permeability of foundation: 4 x 10-5 m/min

Answer:
The seepage loss per meter length of dam is option 'c' (11.52 x 10-2 m3/day).
