There are three soils from left to right $(1,2,$ and $3).$ The soils have permeabilities k$1=0\mathrm{.}0754989$ cm$/$s$,$ k$2=0\mathrm{.}03797537$ cm$/$s$,$ and k$3=0\mathrm{.}074834$ cm$/$s$.$ The lengths of the three layers are L$1=27$ ft$,$ L$2=43$ ft$,$ and L$3=60$ ft$.$ If the water elevation on the left hd $=36$ ft and the water elevation on the right Hu $=74$ ft$,$ what is the energy drop over the second soil layer $($h$2)$ in feet? The height of the soil layer is $36.$
