Question
Download Solution PDFIn a falling head test, the initial head level is 100 cm and the head level after 100 seconds is 10 cm. The area of cross-section of stand-pipe is 10 cm2, and the area of cross-section of soil sample is 100 cm2. Find the permeability of soil sample if the length of sample is 20 cm.

For falling head permeability test
Where
k = Coefficient of permeability,
a = Area of stand pipe = 10 cm2
A = Area of soil specimen = 100 cm2
L = length of soil specimen= 20 cm
h1 and h2 = initial and final head level = 100 cm and 10 cm respectively
t = time required for head fall from h1 to h2= 100 sec
