EX$-2$: The water table $3000ft$ away from a lake has an elevation of $64ft.$ Use Darcy's law

to find the velocity of the groundwater $3000ft$ away from the lake. the elevation of the

lake is $60ft,$ and the soil surrounding the lake is a fine sand.

$K=5\frac{m}{d}ay(1f\frac{t}{0\mathrm{.}3048}m)=16\mathrm{.}4f\frac{t}{d}ay$
