Topic: Agitation
A flat-blade turbine agitator with disk having six blade is installed in a tank. The tank diameter (Dt) is 1.83 m, the turbine diameter (Di) is 0.61 m and the width (w) is 0.122 mm. The tank contains four baffles, each having width (J) of 0.15 mm. The turbine operate (N) at 90 rpm and the liquid in tank has a viscosity (u) of 10 cP and a density (p) of 929 kg/m3. It is desired to design a small pilot unit with a vessel volume (V) of 2.0 L so that effects of various process variables on the system can be studied in the laboratory. The rate of the mass transfer appear to be important in this system so the scale-down should be on this basis. Design the new system specifying sizes, rpm and power.
Include all calculations and graphs if possible . Thank you.
