The association between Discharge velocity (v) and seepage velocity (vs) through soils are given below as options. Choose the correct one.
1
Seepage velocity (vs) is always greater than discharge velocity (v)
2
Discharge velocity (v) and seepage velocity (vs) are related as v = e.vs, where e is the void ratio of soil
3
Seepage velocity (vs) is always less than discharge velocity (v)
4
Discharge velocity (v) and seepage velocity (vs) are related as vs = n.v ; where n is the void ratio of soil
