A beaker is filled with a liquid of density ρ1 up to a certain height. A is a point, h m downwards from the free surface such that the pressure at A is P. If the liquid is replaced by equal volume of another liquid of density ρ2, at what distance from the free surface will the pressure be P now?
I have been asked this question in a national level competition.
My question is taken from Pressure Distribution in a Fluid topic in chapter Pressure and Its Measurement of Fluid Mechanics
