heat transfer is heat transfer, if it transfers 100kW of heat (100kJ per second) that's what it transfers, doesn't matter what the mass rate is. This is taught in ME's first thermo class..... I could do the PVC thing, but i'm not quite backyard mechanic enough to run around with that on my car
. So am I right is there no K&N CAI for these cars? Someone tell me otherwise...
I got a engineer friend who has made his living for many years in
the Automotive Air Conditioner field.
Of course he has had to deal with air flow in pipes, heat exchange
rates and the like.
He and I have had discussions about air intake systems many times. We
even used some of his air flow meters and equipment to test various bends,
convoluted tubing like Ford uses, and that kind of stuff to arrive at some
interesting findings for use on home made air intake systems
When I said the air flow would not be effected by the engine bay
heat at WOT, I based my info upon what I have learned from my
friend.
I called him and told him the application we are dealing with and I
read him your reply.
His answer was a ... quick reply of ... "That Guy Is Correct"
He then said there was a .......... HOWEVER
He said "While that guy has factual info" ... more factual info needs
to be considered in this particular application.
He explained about laminar air flow. It is a layer closely hugging
the outer most part of the pipe. It actually does not flow and it is
that outer thin layer that the heat is transfered to just as you
have talked about.
Since our length of pipe is quite short and the heat is only transfered
to that thin layer that hugs the pipe ... he says the bulk of the air mass
is flowing and if it is effected by engine bay temps at all ... its very little.
It is not my intention to argue or be on the offensive here
The info you shared ... seemed to me ... to be factual
I always gotta dig deeper when I see things along these lines
In this case ... it seems you and he both have good info
and
A whole bunch more of it than me
