Rotating water with oil - Centrifugal force for each liquid

Conclusion: Density of each liquid does not affect the result. For mathematical proof, apply Euler's formulas for a random point in each liquid: ∂P/∂r= ρ * ω^2 * r ∂P/∂z= -ρ g As a conclusion: z1 = H1 - ω^2*R^2/4g ω^2*r^2/2g z2 = H2 - ω^2*R^2/4g ω^2*r^2/2g **P = Pressure r = radius of random point ρ = density ω = angle of random point z = distance from the bottom for each random point H = volume of each liquid
