Question
In a falling head permeability test, the following data was obtained: diameter of standpipe = 1.5 cm;
diameter of sample = 10.16 cm; height of water level at beginning of test (h1) = 30 cm; length of sample
(L) = 20 cm. The soil had a coefficient of permeability (k) equal to 3.4 x 10°cm/sec. If the test was
conducted for a period of 8 hours, what was the water level at the end of the test (h2)?
