An experimental setup in the laboratory is shown. Two
50 mm diameter soil samples A and B are placed under
constant head. (All dimensions are in mm.) The
permeability of sample A is twice that of sample B.
Assuming the tail water level as the datum, what is the
total head at the interface between the soil samples? If
200 ml of water flows through the sample in 5 minutes,
determine the permeabilities of the two soil samples.
