Question $3$

a$)$ Figure $1$ shows a sand column, drawn to scale, with cross$-$sectional area $A=1m^2$ through

which steady state vertical flow is occurring. The hydraulic conductivity of the sand, $k={10}^{-6}$

$\frac{m}{s}.$ Complete the following table with respective values of pressure head, elevation head and

total head at points $A,B$ and C $.$

rigutes

b$)$ Water flows through a $4$ m soil sample in various configurations as shown in Figure $2$ below

with cases $($a$),($b$)$ and $($c$).$ The permeability of the soil is $0\mathrm{.}1c\frac{m}{s}.$ Determine the pressure head,

the elevation head and the total head at the entering end, X $,$ the exit end, Y and at the

intermediate point A of the sample as well as the discharge velocity, $v$ in each of the cases.
