Pick up the correct statement from the following:
Answer & Solution
Correct Answer:
Option
D
As the size of the sewer increases, the velocity of the flow decreases because the flow is spread over a larger cross-sectional area.
This decrease in velocity can lead to deposition of solids, as the flow may not be strong enough to carry the sediment through the sewer.
Therefore, in larger sewers, there is a higher likelihood of deposition taking place.

LoginSo, more the dia, more will be the velocity at flat Gradient. And less dia less velocity..
I think all options correct except D...
If the velocity is less means little more sludge deposition occurs.
So, D is the correct one.
