Where do you take that from? As far as I know (mostly from my thermal transfert class), the efficiency of an heat exchanger (a rad for exemple) will not have a maximum, but rather an asymptotic evolution pass a certain point. (i.e. the efficient will still improve but with a very slow slope). That is, looking at the rad alone.
Also, what do you mean by speed? Velocity? If that's the case, then how can you say that the change will be minimal within the entire loop? Especially with all those wbs using impingement (sp?) plate.
P.S. not sure asymptotic is a word, might have just made it up from french! :P
