Question

5. A falling head permeameter was used to determine the permeability of a sandy-clay soil sample having a cross sectional area of 12.56 cm2 and a length of 18 cm. The cross-sectional area of the permeameter standpipe is 2 cm*. The time during which the level of water in the standpipe ction 22035 TR 0925-1040 NCE 3610 Homework Set 2 Spring 2019 dropped from 100 to 50 cm was 4 minutes. Determine the coefficient of permeability of this material.
