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 ω2 r P, z ρ g As a conclusion: z1 H1 ω2R2, 4g + ω2r2, 2g z2 H2 ω2R2, 4g + ω2r2, 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
