Question 12 Water is flowing downwards through a vertical sand column as shown in Figure 6. The length of the column L 160 cm, the cross-sectional area A 220 cm2, the head difference Ah 130 cm (assume this head difference is constant). The sand in the column has a hydraulic conductivity k 25 m/d and the porosity n=0.32. Determine the steady state seepage velocity of soil. Page 5 of 14 Soil sample area A 220 cm Pemeability k 25 m/day...

Problem 3: A constant-head permeability test was performed on the soil sample shown below. The hydraulic conductivities were 0.04 cm/s for the sand and 0.0004 cm/s for the silt. The cross-sectional area of the sample is 10 cm², of which 9 cm' is sand and the remainder is silt. (a) Plot how the total hydraulic head (expressed in terms of AH) and hydraulic gradient vary along the length of the sample. (b) What would be the hydraulic conductivity (k) for...

[15) 3. Two lines of sheet pile walls are driven into a river bed to allow excavation of a trench. Water level in the trench is maintained at the bottiom of the excavation (level C-F) by pumping Elevations are as follows: Impervious layer (level E-G; datum): Oft Soil surface (level B-B') Water level & soil level in trench (C-F): 40t Water level in river (A-A'): 75 t Tip of...

Problem 3 A pipeline delivers water from Reservoir 1 to Reservoir 2 as shown in the following figure. The water levels at Reservoirs 1 and 2 are 50 ft and 20 ft, respectively. A globe valve is installed in the pipeline with a minor head loss coefficient k 10. The pipe from Reservoir 1 to the globe valve is 1000 ft long and 6 inches in diameter. The pipe from the globe valve to Reservoir 2 is also 1000 ft...
