Problem $6$

Refer to the figure below. Find the flow rate in m$3/$sec$/$m length $($at right angles to the cross

section shown$)$ through the permeable soil layer. Given: H $=6$ m$,$ H$1=3\mathrm{.}0$ m$,$ h $=3\mathrm{.}2$ m$,$ L $=65$

m$,\backslash$alpha $=5\backslash$deg $,$ k $=0\mathrm{.}04$ cm$/$sec$.$Impervious layer
