Suction Baffles Needed?

[esass13]

How do I determine if baffles are needed in a wet well? I have multiple suction flanges along 1 wall of a rectangle wet well. I see how to calculate all the needed dimensions for a baffle, BUT how do I figure if a baffle is actually needed?

thanks

Complex issue. Follow pump to pump spacing recommendations. Otherwise, there's no real way to tell other than "feeling" or a CFD analysis. If you don't get "the feeling" or CFD analysis, put in the baffles and maintain baffle wall minimum distances to each individual pump.

What size pump units are you talking about - flow rates / pump or inlet diameter, what is the spacing between intakes, what is the submergence and how far from the back wall are the intakes etc
