The critical exit gradient differs from the critical hydraulic gradient.

Critical exit gradient is the ratio of seepage head loss to the length of seepage it means it not related to specific gravity or voids ratio.

It is directly proportional to head loss and inverse to the length of seepage.

Thanks.

Exit gradient= G-1/e+1.

So, the options C and D both are right.

It's increase with decrease in void ratio.

We always neglect constant for defining proportionality relationship. As here answers are more than one hence answer is none of above.

Its has directly proportional to G and inversely proportional to E. So answer should be c and d. But there is no this type of answer so it will non of these.

Anyone, explain the difference of the critical hydraulic gradient and exist gradient.

Gaurav said:   5 years ago
Right @Dipu Bunku Rose.

It's critical exit gradient, not critical hydraulic gradient.

Seepage velocity = velocity gradient/porosity.

So, Answer E is correct.
