Given: H1 = 1.5 m; H2 = 2.5 m; h = 1.5 m; area of the tank = 0.62 m?: void ratio of the soil, e = 0.49: G. = 2.66; and hydraulic conductivity of the sand (k) = 0.21 cm/sec. a. What is the rate of upward Valve fopen) seepage? b. Will boiling occur when h =1.5 m? Explain. c. What would be the critical value of h to cause boiling? Inflow Ans.: (a) q = 781.2 cm'isec, (b) No. (c) h = 2.77m 5.17 Refer to Figure of Problem 5.16. If H, = 0.91 m, H2 = 1.37 m. h =0.46 m, Ysat = 18.67 kN/m, area of the tank = 0.58 m2, and hydraulic conductivity of the sand (k) = 0.16 cm/sec, a. What is the rate of upward seepage of water (m/min)? b. If the point C is located at the middle of the soil layer, then what is the effective stress at C? Ans.: (a) i= 0.336, (b) q = 0.0187 m/min 5.18 A cut is made in a stiff, saturated clay that is underlain by a layer of sand. What should be the Y= 19 kN/ height of the water 4/14 7.
