Question

Illustrated laboratory setup includes a column of homogenous soil with a square cross-section area of 25 cm2. A constant head difference is applied for the setup. Assume continuous, steady-state flow in a fully saturated medium, and all head loss occurs in the soil. Points A, B, and C are located as shown in the figure. The saturated unit weight of sand is 18 kN/m3.

a) Determine the elevation, pressure and total head at Points A and B.
b) Determine the hydraulic gradient.
c) Determine the total amount of flow per minute if k = 10 cm/min
d) Show the direction and calculate the seepage force acting on plane x-x.
e) Calculate the effective stress along the plane parallel to the direction of flow assuming that the total stress along that direction is 25 kPa at Point C.
