A water spray gun is attached to a hose of cross sectional area $\displaystyle 30 \mathrm{~cm}^2$. The gun comprises of $\displaystyle 10$ perforations each of cross sectional area of $\displaystyle 15 \mathrm{~mm}^2$. If the water flows in the hose with the speed of $\displaystyle 50 \mathrm{~cm} / \mathrm{s}$, calculate the speed at which the water flows out from each perforation. (Neglect any edge effects)
