Absolute Permeability of Soil at 20°C
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.
Answer:
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.
