Swap Erlenmeyer flasks after a predetermined time interval $($i$.$e$.,5$ min $)$ and determine the weight of the water.

Repeat the last step until you get three consistent readings in a row.

Compute the weight per time and the flux to complete the data table.

$2\mathrm{.}4K_s-$Calculation

We use Darcy's law to calculate the saturated hydraulic conductivity. Darcy's law is defined as:

$q=K_s\frac{{}_H}{L}$

After rearrangement, the saturated hydraulic conductivity can be calculated as:

$K_s=\frac{q*L}{{}_H}$

Report the saturated hydraulic conductivity in $c\frac{m}{m}in.$ Hint: The water is ponding $4\mathrm{.}6$ cm high over the sample. Use this ponding depth and the length of the sample to calculate ${}_H.$
