Question:

Refer to Figure 9.4a. If H1 = 0.91 m, H2 = 1.37 m, h = 0.46 m, (`sat = 18.67 kN/m3, 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 (m3/min)?
b. If the point C is located at the middle of the soil layer, then what is the effective stress at C?
