The impeller in question for mixing action is of the most straightforward geometrical configuration being cylindrical. The computational-algorithmic coding culminated in the determination of more or less accurate numerical values of the drive shaft optimal diameter and optimal values of the following parameters: mixing rod diameter, mixing rod length, clearance space between mixing rod end and the internal drum surface, the power required for mixing action. Analysis of the computational results confirmed that the clearance space of 0.05m and 0.15m produced the best optimal results for design and process variables for the determination of optimum power required for mixing action. The optimum power for mixing action increases as the clearance between the end of the mixing rod and the drum internal surface decreases. The mixing drum diameter is a composition of the clearance space, mixing rod diameter and the mixing rod length. The analytical value of the mixing drum diameter is all-inclusive at the clearance space of 0.05m and 0.15m. Keywords: optimal power requirement; mixing action; impeller; cylindrical; algorithmic coding; accurate numerical values; and mixing drum diameter. 1.
