A lake of depth 15 m is filled with water up to a depth of 10 m from the Bottom of the lake. Soft clay is present below the bottom of the lake up to a certain depth of more than 20 m. Submerged unit weight of the clay is given as 9.5 kN/m3. Take γw = 10 kN/m3. Calculate the effective Stress (kN/m2) at a depth of 15 m below the bottom of the lake.
    Correct answer is between '142,143'. Can you explain this answer?

    γ’ = γsat - γw
    γsat = γ’ + γ= 9.5 + 10 = 19.5 kN/m3
    σ’ = σ - u
    At at depth of 15 m below lake
    σ = γ× 10 + γsat × 15
    σ = 10 × 10 + 19.5 × 15
    σ = 392.5 kw/m2
    u = 25 × γw = 25 × 10 = 250 kN/m2
    = σ - 4
    = 392.5 - 250
    = 142.5 kN/m2
