If porosity of a soil specimen is 50%, then the seepage velocity is
- Asame as superficial velocity
- Btwice the superficial velocityCorrect
- Chalf the superficial velocity
- Dnone of these
Solution
Concept
Seepage velocity
Formula
vs = v/n
Step-by-step solution
1. vs = v / n = v / 0.5 = 2v.
Explanation
Seepage velocity is greater than the superficial velocity.
Why the other options are wrong
It is not equal or half.
Shortcut
vs = v/n.
Correct answer: B) twice the superficial velocity
