A soil deposit has three distinct horizontal layers stacked vertically. The top layer is 2 m thick with a permeability of 4 m/day, the middle layer is 1 m thick with a permeability of 2 m/day, and the bottom layer is 1 m thick with a permeability of 4 m/day. What is the average equivalent permeability (in m/day) of the entire deposit for water flowing normal to the bedding planes?
