In a constant head permeameter with cross section of 10 cm2, when the flow was taking place under a hydraulic gradient of 0.5, the amount of water collected in 60 seconds is 600 cc. The permeability of the soil is
-
- 0.002 cm/s
- 0.02 cm/s
- 0.2 cm/s
- 2.0 cm/s
Correct Option: D
Q = kiA
| Q = | = 10 cm3/s | 60 |
∴ 10 = k × 0.5 × 10
∴ k = 2 cm/s
