In a constant$-$head permeability test in the laboratory, the following are given: $L=265mm$ and $A=97c{m}^2.$ If the value of $k=0\mathrm{.}015c\frac{m}{s}$ and a flow rate of $7,500c\frac{m^3}{h}r$ must be maintained through the soil, what is the head difference, $h($in $cm),$ across the specimen?

$h=,cm$

Also, determine the discharge velocity under test conditions. $($Enter the magnitude in $c\frac{m}{s}.)$

$s\frac{m}{s}$
