Problem $1$

A pervious soil layer is sandwiched between two impervious layers as shown in Figure. Find the rate of flow in $\frac{m^3}{s\frac{ec}{m}}($at right angles to the cross section$)$ through the pervious spi$[$layer$.$ Given: $H=4\mathrm{.}5m,H1$

$=1\mathrm{.}65m,$

$h=2\mathrm{.}8m,S=32m,=12,$ and $k=0\mathrm{.}055c\frac{m}{sec.}$
