Find the seepage through the earth dam shown below in gallons/day if the sieve analysis shows the D10 to be 0.17 mm, and the dam is 1,200 feet wide. What is the pressure head at the top of the aquiclude and at mid-dam (point A)? Number of flow channels N, = 3 Number of equipotential drops N = 7 Using Hazen's formula k = CD? =15D, =15(0.17mm)² = 0.43m sec Note: 8
