(1) Determine the pressure, elevation, total heads and head loss at points A through E in centimeters of water, and plot these values versus elevation. 1 (2) If the diameter of the soil cylinder is 0.6 m and 4.25x 102 m' water flows through the soil sample in 5 min, calculate the coefficient of permeability of the soil and the discharge velocity. (3) A 20 cm long cylinder sample with the diameter of 6 cm is taken from the soil colume in Figure 2. If the dry weight of the soil sample is 9.33 N, and the specific gravity of soil particles is 2.70, calculate the seepage velocity.
