Hydraulic Conductivity

Hydraulic conductivity is a property of vascular plants, soils and rocks that describes the ease with which a fluid (usually water) can move through pore spaces or fractures. It depends on the intrinsic permeability of the material, the degree of saturation and the density and viscosity of the fluid.

Hydraulic conductivity equals the product of the acceleration due to gravity, intrinsic permeability of the medium and fluid density divided by dynamic viscosity.

Formula

QuantityVariable["K", "Speed"] == (Quantity[1, "StandardAccelerationOfGravity"]*QuantityVariable["κ", "HydraulicPermeability"]*QuantityVariable["ρ", "MassDensity"])/QuantityVariable["η", "DynamicViscosity"]
