Exit gradient depends upon head loss and seepage length
The total head loss H between the last two equipotential lines is 0.62 m. The distance between the two equipotential lines on the downstream end in the X area is 3.3 m.
The exit gradient is then computed as 0.62 divided by 3.3 making the upward gradient 0.19.

Value of critical exit gradient is 1. So it doesn't depend on any factor. Hydraulic gradient depends on Specific gravity and void ratio.

Seepage velocity = velocity gradient/porosity.
So, Answer E is correct.
So, Answer E is correct.

Right @Dipu Bunku Rose.
It's critical exit gradient, not critical hydraulic gradient.
It's critical exit gradient, not critical hydraulic gradient.

In question, it is Ie, not Ic.

I guess it's inversely proportionally to void radio.

Directly proportional to G and also inversely proportional to e.
Both C & D are correct for this question.

@All.
You may plot the variation of the critical gradient by keeping G or e constant.
You will find a straight line in the graph paper. So we can say that the critical gradient is directly proportional to G or e. So, the Correct answer is c & d.

It is Directly proportional to potential head.
