Question

In a hydraulic conductivity study, a 15 cm thick water-saturated soil layer was allowed a 15 cm water layer above it vertically, and the water was allowed to pass through the soil for 45 minutes. A total of 540 cc of water was collected. The cross-sectional area of the soil layer was 30 cm². Calculate the discharge rate of flow of water through the soil.

• A. 6.0 cm/h
• B. 12.0 cm/h
• C. 18.0 cm/h
• D. 24 cm/h

Hint:

To calculate water flux $v$ (velocity) directly, divide the total volume by the product of area and time: $v = \frac{\text{Volume}}{\text{Area} \times \text{Time}}$. This is independent of Darcy's gradient.

Answer 1

The Correct Option is D
