How to calculte the power of Agitator

[piestro]

Hi

I have to select the agitator among 3 vendors but one quote 125 hp, other 60 hp and the other 30 hp. I want to know if there are some formula to quick calc about the agitator power.
I need a number of reference.

Thanks in advance.

Chemical Engineeering magazine has a reprint titled "Liquid Agitation" by folks at Chemineer.

Good luck,
