The vessel diameter DT was 0.10 m and the impeller diameter Di was one-half of the vessel diameter DT. In the vertical stirred vessels with three multiple impellers, the relationship of the backflow rate f to the feed flow rate q and the exchange rate Q was established as f=Q−q/2. The exchange rate Q increased in proportion to the stirring speed of impellers n and the opening ratio of a perforated partition plate Ar. The value of the modified dimensionless exchange rate in the vertical vessels with three impellers Q/(nDi3Ar) was proportional to the agitated Reynolds number NRe to the power of 0.20 when the range of the agitated Reynolds number NRe was 1×103 to 6×103, and it was almost constant at 0.17 when the agitated Reynolds number NRe was greater than 6×103.},
