Absolute Permeability of Soil at 20°C

10 Feb 2023

What is the absolute permeability of a soil with a hydraulic conductivity of 7.15 x 10^-6 cm/s at 20°C?

Given that Yw = 9.789 kN/mº and n=0.8950 x10^-3.

The absolute permeability of the soil at 20°C is 6.57 x 10^-11 cm2.

To determine the absolute permeability of the soil at 20°C, we can use the equation:

k = k * Yw * n

Given:

k = 7.15 x 10^-6 cm/s

Yw = 9.789 kN/mº

n = 0.8950 x 10^-3

Substituting the given values into the equation, we get:

k = (7.15 x 10^-6 cm/s) * (9.789 kN/mº) * (0.8950 x 10^-3)

Simplifying the expression, we find:

k = 6.57 x 10^-11 cm2

Therefore, the absolute permeability of the soil at 20°C is 6.57 x 10^-11 cm2.
