The association between Discharge velocity (v) and seepage velocity (vs) through soils are given below as options. Choose the correct one.
Seepage velocity (vs) is always greater than discharge velocity (v)
Discharge velocity (v) and seepage velocity (vs) are related as v = e.vs, where e is the void ratio of soil
Seepage velocity (vs) is always less than discharge velocity (v)
Discharge velocity (v) and seepage velocity (vs) are related as vs = n.v ; where n is the void ratio of soil
Correct answer
Seepage velocity (vs) is always greater than discharge velocity (v)
The samples of burnt clay bricks from five different agencies (S1 to S5) are tested and the results are tabulated as follows. The criteria to be adopted (% water absorption and compressive strength) correspond to the usage of bricks of class designation 15 and above, as per IS 1077 : 1992. Which samples are recommended for wall construction?
| Id | Water absorption (%) | Average Compressive strength (kN/m2) |
|---|---|---|
| S1 | 20 | 18000 |
| S2 | 12 | 15700 |
| S3 | 24 | 10100 |
