Both c & d correct.

And is right.

Because exit gradient is headloss divided by length.
Smarty said:   7 years ago
It is Directly proportional to potential head.

@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.
OPSE AEE said:   6 years ago
Directly proportional to G and also inversely proportional to e.

Both C & D are correct for this question.

The critical Exit Gradient is Directly Proportional to Specific gravity and Inversely proportional to void ratio.

I = (G-1)/(1+e).

In question, it is Ie, not Ic.
Gaurav said:   5 years ago
Right @Dipu Bunku Rose.

It's critical exit gradient, not critical hydraulic gradient.
Ajay said:   5 years ago
Seepage velocity = velocity gradient/porosity.

So, Answer E is correct.
Dewan said:   5 years ago
Value of critical exit gradient is 1. So it doesn't depend on any factor. Hydraulic gradient depends on Specific gravity and void ratio.
