Feeding tubes adverse effects

Obviously the latter criterion is much more conservative than the former one. This would result in even larger reactors on the larger scale. Moreover a situation could occur where the parameter (p becomes > 1, which would have an adverse effect on the meso-mixing (see section 4,2,2,4), Bourne pointed out however, that a considerable gain in possible reactor capacity is obtained by using multiple feed tubes. When the feed tube diameters are increased proportionally to the scale of the reactor, the scale-up criterion for reactors with feed tubes is...
