A clay sample was consolidated in a triaxial cell under a backpressure of 50 kPa and cell pressure of 150 kPa. The drainage valve was then closed and the cell pressure was increased to 200 kPa when the pore pressure increased to 98 kPa. What is Skepton’s B-parameter? The above sample was then subjected to a vertical deviator stress, which was increased from zero under undrained conditions.

Assuming the clay is normally consolidated, find the friction angle in terms of effective stresses.
Prob. A falling head permeability test was performed on a sample of silty sand. The time required for the head to fall in the standpipe from the 60 cm to 30 cm mark was 70 minutes. The sectional area of the standpipe was 1.25 cm?. If the height and diameter of the sample were respectively 100 mm and 90 mm, determine the value of K.
