Re: How do I calculate the agitator power in terms of increasing volume?6 July 2010 at 1:29pm
The high viscosity, 30,000 cp, you describe does not require baffles, but does not increase the power requirements much either. The power requirement for a retreat-curve impeller (RCI) at 96 rpm is about 5,800 Watts. Increasing the volume will have little effect on the amount of power required for the impeller.
How do I calculate the agitator power in terms of increasing volume? Here are the specs: Diameter of reactor - 1.95m Diameter of agitator - 1.1m Speed - 96rpm volume of rector - 6.3 kL volume of material - 3.75 kL Viscosity of material - 30000 cp Density of material - 800 kg/m3 Reactor type -- GLR Agitor type - 3 blade propeller with no baffles What is the power consumption of this volume? I am increasing the volume of material up to 5 KL. What is the power consumption in the same reactor, same material?
Have an insight or suggestion?
