Figure RE6.17 shows seepage taking place beneath a sheet pile in a silty sand, where the hydraulic conductivity is 2 × 10−3 cm/s and the saturated unit weight is 19.5 kN/m3 . Some equipotential lines have been drawn in the figure at total head intervals of 0.5 m. a. Complete the flow net. b. Determine the flow rate in m3 /day per m. c. What is the safety factor with respect to piping? d. Find the pore water pressure at the tip of the sheet pile.
