A constant-head permeability test is performed in a laboratory where the soil sample is 25 cm in length and 6 cm²
in cross section. The height of water is maintained at 2 ft at the inflow end and 6 in. at the outlet end. The quantity of water flowing through the sample is 200 ml in 2 minutes.

(a) Make a sketch of the described conditions.

(b) What is the coefficient of permeability in millimeters per minute?
