WebApr 7, 2006 · It is known that flow number varies with Reynolds number; that is, in the laminar flow regime, it decreases as the Reynolds number is reduced. It is therefore not surprising to see that K S decreased as viscosity was increased in experiments, using glycerol–water solutions, and operating the agitator (a Lightnin A310 axial flow impeller) … WebAgitator designed for low-viscosity products. The speeds available range from 400 to 1,800 rpm, depending on the diameter, with a typical peripheral velocity of between 3 and 15 m/s. According to the agitator's speed, the agitation system generates a high product recirculation flow rate inside the tank.
