A test is set up as shown. A cylindrical mold 4" in diameter is filled with silt to height of H1=0.2ft whose coefficient of permeability is 3.6x10^-4 ft/min. A second coaxial mold is placed on the top of the first mold whose inside legs of the square tube is 1.5" and whose height is H2=0.3ft. Its thickness is negligible. The inside of the second mold is filled with sand whose coefficient of permeability is 2.7x10^-3 ft/min but the outside of the second mold is filled with the same silt. The test set up is constant head. Water is placed on molds and maintained at the level 1.25ft above the level of outlet. It may be consider that the system consist of fictitious soil of thickness H1+H2 and the coefficient of permeability of both soils is Kf. What will be the total flow of water in ft^3/min?
