Let's say I want to scale-up a reaction rom lab scale to pilot scale, there are defined parameters (Re, P/V etc) to get the RPM and power. Now my doubt is, How do I choose type of agitator, and how should I compare between different type of agitator?

Don't know if this came through or not. So try again.  First try is a Mixer /
reactor manufacturer.  They can take your reaction and recommend a type of reactor as well as a way to try it.  This will be quite expensive.

Then  there are customs mixers.  They will take your materials, in the pilot scale, and run it for you.  Again, typically, quite expensive.

Good luck with your project!

You never can tell.  Sometimes, the transition from lab scale to pilot to production is seamless with no issues.  On the other hand, there have been many times when the transition from lab scale to pilot scale was.a royal pain in the butt.  Keep your eyes open and look for anything out of the ordinary and you should be ok.  But yes, bad things can happen...
