Problem The saturated soil specimen shown below has a permeability of 0.005 cm/sec, a porosity of 38%, and a cross-sectional area of 22 cm². Two standpipes are placed at points A and B as shown below. The specimen has reached a steady state condition after flushing it with water for 1 hr. Datum ttttt h₁ = 100 cm 50 cm L = 50 cm B 40 cm h₂ = 80 cm Determine: 1. 2. Elevation head (in cm) at points A and B. Pore water pressure (in kPa) at points A and B. 3. Discharge velocity (in cm/sec) through the sample. 4. 5. What is the quantity of flow through the sample in cm³/day? What is the magnitude of the seepage velocity (in cm/sec)? OUT
