A 1000-L liquid–liquid mass contactor is equipped with a Rushton turbine of diameter L_p
= 0.5 m (both the tank height and diameter are 1.08 m). The dispersed and continuous phases both have a density of 1200 kg/m³. The interfacial tension is 3.0 × 10⁻³
N/m. The mixer is a variable-speed motor and drive that is capable of impeller speeds between 40 and 70 rpm (0.67–1.17 s⁻¹). What range of drop sizes can be produced?
