A tank of total height 5 m is filled with sand of thickness 3.5 m having void ratio and specific gravity of 0.65 and 2.78, respectively. Remaining portion of tank is filled with water. The pressure head at the bottom of tank is 7.2 m. Assume unit weight of water is 10 kN/m³. The effective stress at a point 3 m below the top of the tank is kPa. (Round off to two decimal places).
