EARTH458 Lecture Notes - Lecture 4: Hydraulic Conductivity, Fluid Dynamics, Turbulence

EARTH 458 week 3.3 part 1

Define laminar and turbulent flow in terms of the Reynolds number and kinetic and frictional

heat loss:

Laminar flow is when R < 10

Transient flow is when 10 < R < 2000

Turbulent flow is when 200 < R

Describe geologic situations where Darcy’s Law is not valid:

K= hydraulic conductivity

a. Which components of the media affect hydraulic conductivity?

Intrinsic permeability or permeability

Sand vs Clays

Cd^2 = Kp L^2 permeability: lowercase k: k=cd^2 (L^2) or units of darcy (check
