A permeable soil layer is underlain by an impervious layer, as shown in Fig$\mathrm{.}2.$ If $H=4\mathrm{.}2m,=10o,$ and $k=6\mathrm{.}810-4c\frac{m}{sec}$ for the permeable layer, calculate the rate of seepage through it in $\frac{m}{h}\frac{r}{m}$ width.

Using Fig. $3,$ Find the flow rate in $\frac{m_3}{s\frac{ec}{m}}$ length through the permeable soil layer. Given: $H=5\mathrm{.}5m,H_1=3m,h2\mathrm{.}8m,L=52m,=5o,k0\mathrm{.}05c\frac{m}{sec}.$
