Permeability

Due to rise in temperature, viscosity and unit weight of a fluid percolating through a soil mass, are reduced to 80% and 90% respectively, if or factors remain unaltered, coefficient of permeability

Increases by 12.5% Decreases by 12.5% Increases by 28% Decreases by 28%

Concept:

The coefficient of permeability ‘k’ is given by:

$k = C \times \frac{γ}{μ} \times \frac{e^{3}}{1 + e} \times D^{2}$

where

e = void ratio

D = effective size of soil particle

γ = weight density of fluid

μ = viscosity of fluid

c = constant (depends upon the shape of particle)

Calculation:

Given,

Viscosity reduced to 80% i.e μ₂ = 0.8 μ₁

Unit Weight reduced to 90% γ₂ = 0.9 γ₁

As 'k' is directly proportional to γ / μ

∴ $\frac{k_{2}}{k_{1}} = \frac{γ_{2} \times μ_{1}}{γ_{1} \times μ_{2}} = \frac{0.9 γ_{1} \times μ_{1}}{γ_{1} \times 0.8 μ_{1}} = 1.125$

k2 = 1.125 k1

i.e k2 is increased by 12.5%.
