****PROVIDE STEP BY STEP SOLUTION SOLVING H1 AND H2 VALUES in part B***** 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. Provide step by step solution. 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, provide step by step solution solving h1 and h2 values.

A fine sand was tested in situ to give a coefficient of permeability of 3.7 x107 m/s. A sample of the same sand, 400mm high and 100 mm in diameter was then tested in a constant head permeameter. Water percolated through the soil under a head of 600mm for 5 minutes and the discharge water had a volume of 1300mm. Determine whether the in situ testing was reflected by the laboratory results and If the below water retaining structure is 140m in width, based on a coefficient of permeability of 7.8x10°m/s, determine the quantity of water that will flow through the soil and under the structure per day.
