Explanation:
Constant Head Permeability Test (Coarse Grained): The constant hydraulic gradient i causing the flow is the head h (i.e., difference in water levels of the overhead and bottom tanks) divided by the length L of the sample. ... If Q is the total quantity of flow in a time interval t, we have Darcy's law.
