Anyone have a formula for determining the required flow rate for obtaining a whirlpool for a given volume of liquid?
(I'm looking at pump sizing for getting a proper whirlpool going.)
I've seen a few people use "whirlpool chillers" in a "normal" kettle -can these things get as good of a whirlpool going as a kettle that was designed as a combi kettle+whirlpool with a tangential inlet? Pros / Cons for either method?
-Is there any benefit to stepping down the size of your whirlpool inlet from the typical pump 1/2" fitting? (Does a smaller ID increase velocity and contribute to a better whirlpool?)
Where should the liquid "out" in a flat-bottomed whirlpool be located to maximize tank drainage while minimizing picking up hop crud /break material?
Is there much point in whirlpooling if you use whole hops or is this really a pellet-only affair?
How much will a electric heater element and immersion chiller impact your ability to get a good whirlpool going?
Thanks!
