1. The problem statement, all variables and given/known data The container of uniform cross section area A holds two immiscible non-viscous incompressible liquids of densities d and 2d each of height H/2. A tiny hole of area S<<A is punched on the vertical side of the container at height h(<H/2) Find the speed of efflux. 2. Relevant equations 3. The attempt at a solution I know how to find it when there is only one liquid present. What is the approach in this case?
