A full scale agitation system that has a flat blade turbine impeller with six blade-disk is used in a mixing operation. The (Da/W) and (D/J) values are 5 and 12, respectively. The liquid level is equal to the tank diameter. The liquid in the agitator has a viscosity of 85 cp and a density of 65.5 lb/ft³. The Reynolds number for the agitator is 10,000 and the agitator requires a power of 1 kW. It is desired to scale down the system for a vessel whose production volume is 4 times smaller than the original full scale agitation system. Assume mass transfer similarity for the scale down process. Calculate the power requirement in kW for the scaled down tank. Problem 2. 4
