i) A pipe of 1.2 m diameter was provided in a reservoir to act as an outlet. Due to disuse, it was buried and completely clogged up for some length by sediment. Measurements indicated the presence of fine sand (coefficient of permeability, K, = 10 m/day) deposit for a length of 100 m, at the upstream end and of coarse sand (coefficient of permeability, K₂ = 50 m/day) at the downstream end for a length of 50 m. In between these two layers the presence of silty sand (coefficient of permeability, K3 0.10 m/day) for some length is identified. For a head difference of 20 m on either side of the clogged length, the seepage discharge is found to be 0.8 m³/day. Estimate the length of the pipe filled up by silty sand. =
