Question

Consider the following statements:
1. Quantity of seepage in each flow channel of a flow-net is independent of the size of field.
2. Drop in head between adjacent equipotential lines of a flow-net is dependent on upstream head.
3. With increase in the length of a flow path, the corresponding exit gradient will decrease.
Which of these statements are correct?

• A. 1, 2 and 3
• B. 1 and 2 only
• C. 1 and 3 only
• D. 2 and 3 only

Answer 1

The correct option is A 1, 2 and 3

$Dropbetweenequipotentialline=\frac{H}{n}$

Where, H = Upstream head
