A 750 ml of laboratory batch crystallizer with a 3.5 cm diameter is performed at a speed of 600 rpm, the minimum speed required to fully suspend the crystals. Estimate the impeller diameter and speed for scale up to 250 liters for each of the following three basis of scale up techniques. (a) The power per volume. (b) The impeller tip speed. (c) The full suspension of crystals (at minimum speed).
