Water flows through a pipe which initially starts off in region $1$ with a

cross$-$sectional area of A$1=0\mathrm{.}7$ m$2$ and then tapers to a smaller cross$-$sectional

area A$2$ in Region $2.$ In Region $1,$ it flows at a speed of v$1=0\mathrm{.}21$ m$/$s and in region

$2,$ it flows at v$2=2\mathrm{.}5$ m$/$s$.$ The pressure in Region $1$ is P$1=8*103$ Pa$.$ Water is

incompressible so its density stays constant W $=103$ kg$/$m$3.$ Assuming that the $2$

regions are the same height, what is the pressure in Region $2($P
