Calculation of U-bend height
Thread Content
When separating oil from water, a U-bend in the water-side outlet pipeline is often used to control the oil-water interface. How do experts calculate the height of this U-bend?

The pressures on the U-bend side and the separator side are in balance; the pressure at the U-bend represents the static pressure of the aqueous phase, while that at the separator represents the static pressure of both the oil and aqueous phases. At the separator side, ρ1gH1 + ρ2gH2 = ρ2gH3. By specifying the values of H1 and H2 for the separator side, it is possible to determine the value of H3 for the aqueous phase on the U-bend side
