# The Tank's leaking!

A tank with a small hole at the bottom has been filled with water and kerosene (specific gravity=0.8). The height of water is 3 m and that of kerosene is 2 m. When the hole is opened the velocity of fluid coming out from it is nearly: (take g=10 m$$s^{-2}$$ and density of water= 1000 kg $$m^{-3}$$)
