A falling head permeability test is to be performed on a soil sample whose permeability is estimated to be about 3x10-5 cm/s. What diameter of the standpipe in mm should be used if the head is to drop from 27.5cm to 20.0cm in 5 minutes and of the cross-sectional area and length of the sample are respectively 15cm2 and 8.5cm?
The following data are for a falling-head permeability test: Length of the soil sample = 140 mm Diameter of the soil sample = 70 mm Area of the standpipe = 19.6 mm2 At time t =0, head difference = 500 mm At time t = 7 minutes, head difference = 350 mm
FUNDAMENTALS OF GEOTECHNICAL ANALYSIS A constant head permeability test is performed on soil that is 2 cm x 2 cm square, and 2.5cm long. The head difference applied during the test is 20 cm and 7 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 conducted on the same soil specimen at the same time (t1 – t2 = 100 sec), and the standpipe diameter is 0.8 cm. If the average head during the test should be 18 cm, what are h1 and h2 values?
