Problem

A container holds two immiscible liquids: a layer of oil (density

800\,\text{kg/m}^{3}

) of thickness

2\,\text{m}

floating on top of a layer of water (density

1000\,\text{kg/m}^{3}

) of thickness

3\,\text{m}

. A small hole is punched at the bottom of the container (in the water layer). Determine the velocity of efflux of the water. Take

g = 10\,\text{m/s}^{2}
