Three soil specimens ( Soil 1, Soil 2, Soil 3 ), each 100 mm long and 100 mm diameter, are placed in series in a constant head flow set-up as shown in the figure. Suitable screens are provided at the boundaries of the specimens to keep them intact. The values of the coefficient of permeability of soil 1, soil 2, and soil 3 are 0.02, 0.004, and 0.03 cm/s respectively, then
