Review the three cases of flow through porous media shown below. For each case, consider and show/label the total head (z + 2) and hydraulic gradient and explain why or why don't the flow directions (Q) make sense? h₁ h₂ Ah AL Ah AL AL Ah Figure 4 - Different apparatus orientations with the same hydraulic gradient: the gradient magnitude (Ah/AL) is the same in each case and the gradient direction is parallel to the tube in each case.
