Estimating Hydraulic Conductivity of a Sand Sample

How do we estimate the hydraulic conductivity of a sand sample?

Given that 10% of the sample has grain sizes finer than 0.0002 m and the Hazen coefficient is 118.

Estimating Hydraulic Conductivity

The hydraulic conductivity of the sand sample is estimated to be 11.8 meters per day (m/d).

To calculate the hydraulic conductivity using the Hazen method, we can use the formula:

Hydraulic conductivity (K) = (Hazen coefficient) × (percentage of grains finer than a specific size)

In this case, the Hazen coefficient is given as 118, and the percentage of grains finer than 0.0002 m is 10%.

Therefore, the hydraulic conductivity can be calculated as:

K = 118 × 0.10

K = 11.8 m/d

Thus, based on the given information and the Hazen method, the hydraulic conductivity of the sand sample is estimated to be 11.8 meters per day (m/d).
