sci.engr.mech might theoretically be a better place to ask heat transfer
questions, but as far as I can see not too many real experts read that group.
I think most mechanical engineers find the group too boring to bother with -
at least I do (yes, I am a mechanical engineer).
Probably the best bet is to read a book on the subject; I could recommend some
english language books but the OP would probably be better off finding one
written in German.
