$(6$ pts$)$ This pipe is filled with flowing water. The speed through the upper pipe $($location $1)$ is $2\mathrm{.}0$ m$/$s$,$ and the pressure there is $100$ kPa. The lower pipe $($location $2)$ is $0\mathrm{.}5$ meters lower, and has half the radius. Find the pressure in the lower pipe.

$[$Note: the density of water is $1000$ kg$/$m$3.]$
