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