Vessel Mixing Turnover rate

[NCENG78]

Help....I know how to calculate the expected mixing time for a material blend, but my customer is asking me for the mixing turnover time in my vessel. I don't know that I've ever tried to do this. Anybody know how. Nothing funny about my system. 6500 gallon vessel with 4 baffles, bottom impeller is radial and middle one is 4 pitch axial.

dearman,

My understanding of mixing turnover time would be the time it takes the agitator to pump the equivalent of one vessel volume, i.e. turnover the vessel contents.

I have seen the data used as a relative guide to mixing intensity, usually as the number of turnovers per unit of time.

To do this you will need the pumping rate data from the agitator supplier.
