For a falling head permeability test, these value
are given:
Length of the soil specimen = 200 mm
Area of the soil specimen = 1000 mm2
Area of the standpipe = 40 mm2
Head difference at time, t = 0 min is 500 mm
Head difference at time, t = 3 min is 300 mm
1. Determine the hydraulic conductivity of the
soil in cm/sec.
2. What was the head difference at time, t =
100 sec?
