A falling head permeability test was run on a soil sample 9.6cm in diameter and 10cm long. The head at the start of the test was 90cm. The coefficient of permeability of the soil was found to be 5(10)- cm/s. The diameter of the stand pipe was 1cm. a) Determine the flow at the start of the test in cm³/ hr. b) How much head was lost during the first 30min? c) Determine the flow after 30 minutes in cm³/hr.
