Problem $2\mathrm{.}3\mathrm{.}11$

In a certain liquid at rest, measurement of the specific weight at various depths show the given variation:

The depth $h=0$ corresponds to a free surface at atmospheric pressure. Determine, through numerical integration of

$\frac{dp}{dz}=-,$ the corresponding variation in pressure and show the results on a plot of pressure $($in kPa $)$ versus depth $($in

$m.$
