Answer Question 7
7.7 In a constant-head permeability test, the length of the specimen is 200 mm and the cross sectional area is 78.5 cm². If k = 2.1 x 10-2 cm/sec, and a rate of flow of 130 cm³/min has to be maintained during the test, what should be the head difference across the specimen?
Please answer all 1. List the three corrections which should be applied to the hydrometer readings. 2. Why is it important to remove the hydrometer from the measuring cylinder between readings? 3. A hydrometer test has the following results; Gs = 2.70, temperature = 240C, and L = 92 mm at 60 minutes after the start of sedimentation. Calculate the diameter of the smallest-size particles that have settled beyond the zone of measurement at that time (use the table in the lab manual to find, A=0.0128). D(mm) = A sqrt( L(cm) / t(min) )
A cylindrical soil sample with length = 15cm and diameter = 4cm was taken from a site where a groundwater contamination piume was found. The sample was tested in the lab to determine its hydraulic conductivity. A hydraulic gradient of 0.05 was applied across the sample, and a flow rate of 0.025 cm³/sec was measured. Calculate the hydraulic conductivity of the soil sample using Darcy's law.
Q. Solve this seepage problem.
For a falling head permeability test, the following values are given: Length of specimen: 200 mm Area of specimen:1000 sq. mm Area of standpipe: 40 sq. mm Head difference at t= 0: 500 mm Head difference at t= 180 sec : 300 mm Determine the hydraulic conductivity (cm/sec)
