![3.4-2. Power for Agitation and Scale-Up. A turbine agitator having six flat blades and a
disk has a diameter of 0.203 m and is used in a tank having a diameter of 0.61 m
and height of 0.61 m. The width W = 0.0405 m. Four baffles are used having a
width of 0.051 m. The turbine operates at 275 rpm in a liquid having a density of
909 kg/m³ and viscosity of 0.020 Pa -s.
(a) Calculate the kW power of the turbine and kW/m³ of volume.
(b) Scale up this system to a vessel having a volume of 100 times the original for
the case of equal mass transfer rates.
Ans. (a) P = 0.1508 kW, P/V = 0.845 kW/m',
(b) P2
= 15.06 kW, P2/V2 = 0.845 kW/m³
