A wide cylindrical tank with a small opening in the bottom has a water column of height `h_(1)` and above the water column, there is a layer of kerosene oil of thickness `h_(2). The velocity of efflux through the opening is

A wide vessel of uniform cross- section with a small hole in the bottom is filled with 40cm thick layer of water and 30cm thick layer of kerosene.The relative density of kerosene is 0.8 .The initial velocity of flow of water streaming out of the hole is (take g=10ms^(-2) )
