Correlation of maximum stable drop size with volumetric power input for reactor configuration B-3 (3 m3scale) for different aeration rates. Dispersion of paraffin oil in 1 mM PO4-buffer at pH 7.3. Maximum stable drop size measured after 3 h agitation. Solid line represents theoretical prediction based on Eqs. 1 and 2 with ϕ = 6.9.
