In a clayey sandy silt deposit, the water table is 3.5 m below the surface, but the sand to a height of 1.5 m above the water table is saturated by capillary water. The top 2 m of sand can be assumed to be dry. The saturated and dry unit weights of the soil are 19.5 kN/m^3 and 18.0 kN/m^3, respectively. Calculate the effective vertical stress at 8 m below the surface. Express answers in kPa rounded to the first decimal place.
