Textbook Problem

The hydraulic conductivity of a sandy soil is 0.011 cm/sec at a room temperature of 24°C. What would be the hydraulic conductivity at 20°C? Use Eq. (7.15).

To determine

Find the hydraulic conductivity at 20°C temperature.

Explanation

Given information:

The hydraulic conductivity of a sandy soil at 24°C temperature is 0.011 cm/sec.

Calculation:

Determine the hydraulic conductivity at 20°C temperature using the relation.

k20°C=(ηT°Cη20°C)kT°C

Here, (ηT°Cη20°C) is the variation.

Refer the Table 7.2, “Variation of (ηT°Cη20°C)” in the textbook.

Take (ηT°Cη20°C) value as 0
