Which of the following represents the most appropriate/correct condition for the validation of Darcy's law in permeability analysis of soils?
(Where, η = coefficient of viscosity of water, ρ = mass density of water, v = velocity of water and D = average particle diameter)
1
\(\frac{ρ v D}{η}=1\)
2
\(\frac{ρ v D}{η}=2000\)
3
\(\frac{ρ v D}{η}=1000\)
4
\(\frac{ρ v D}{η}=5000\)
