Extracted text: Q.11 Consider the three layered soil strata shown in the figure below. The thickness and coefficient of vertical permeability of each layer is mentioned in the figure. Flow Ah = 0.50 m -3 H, = 3 m K, = 3 x 10° cm/s %3D -2 H2 = 2 m K, = 6.5 x 10 cm/s H = 9 m H3 = 4 m. L = 2 m -4 Kg = 7 x 10 cm/s The total head loss in three layers is
