An agitated cylindrical vessel is fitted with baffles and flat blade impellers. The power number for
this system is given by where P is the power consumed for the mixing, ρ is the
density of the fluid, n is the speed of the impeller and D is the diameter of the impeller. The
diameter of the impeller is 1/3rd the diameter of the tank and the height of liquid level is equal to
the tank diameter. The impeller speed to achieve the desired degree of mixing is 4 rpm. In a
scaled up design, the linear dimensions of the equipment are to be doubled, holding the power
input per unit volume constant. Assuming the liquid to be Newtonian and to be independent of
Reynolds number, what is the impeller speed (in rpm) to achieve the same degree of mixing in the
scaled up vessel?
