Within the bored sample 4 various types of soil was observed. Thus, the permeability tests were conducted 4 times. The data from the permeability tests were provided below, Layer position 1 2 3 4 Grain size observed Coarse Coarse Fine Fine Volume (litres) 2 5 Time-start (s) 0 0 4 9 Time-end (s) 100 160 220 280 Head-start (cm) 0 0 25 18 Head-end (cm) 80 80 10 5 Layer Depth (m) 1.2 2.8 3.6 2.2 For the permeability test setup, the diameter of the chamber storing the sample was 100mm and length was 200mm. Diameter of the standpipe for falling head permeability test was 10mm. Considering the vertical and horizontal permeability values as same, calculate the equivalent vertical and horizontal coefficient for these layers.
