The grain$-$size analysis data for a sand is given in the following table below. The sand has a void ratio of $0\mathrm{.}77,$c $=1\mathrm{.}2,$ SF $=6\mathrm{.}5,$ and grain effective sizes D$10$: $0\mathrm{.}093$ mm$,$ D$3$o: $0\mathrm{.}145$ mm$,$ D$60$: $0\mathrm{.}238$ mm$.$ Estimate the hydraulicconductivity using Carrier's method, Hazen, Chapuis, Amer and Awad methods.
