The comparison of the estimates of d32 (Table 5) and e (Figures 6, 7) relative to the tests with 1 SM (0.4 and 1.3 m/s)
and with mechanical agitation (200 and 400 rpm) is generally in agreement with the observations of Davies, who showed
that, in the formation of liquid–liquid dispersions, static mixing is generally characterized by lower specific energy consumptions and higher drop diameters than mechanical agitation.
