Question: A constant head permeability test is performed on a soil that is 2 cm x 2 cm square and 2.5 cm long. The head difference

A constant head permeability test is performed on a soil that is 2 cm x 2 cm square and 2.5 cm long. The head difference applied during the test is 18 cm, and 5 cm3 is collected over a time of 100 sec.
(a) Compute the permeability based on these test conditions and results.
(b) A falling head test is to be done on the same soil specimen in the same time (t1 - t2 = 100 s) and the standpipe diameter is 0.8 cm. If the average head during the test should be 18 cm what are h1 and h2?
