aaaaarggg damn..... just as I thought I got the thermodynamics all figured out... someone comes along, and re-invent it all, completely not they way I got it.....
so 12v^2, am I getting this right?..... you mean to say the water need to be very much near stagnant inside the block, for it to have enough time to absorb the heat.... ok now...
entertain me for a bit here....
Q:
When is the most heat per time interval going to be moved?
A:
Right at the very first instant the cool water gets into the block.
Reason: (R)
Delta T is at it's max.
Now lets move on to the next instant in time..... 0.000000000091 Nano seconds later.....
Q:
is the heat transfer going to increase or decrease......
A:
decrease...
R:
Delta T is no longer what it was, because the water got some action......
Ok lets move on to the next moment in time....
Q:
The same thing as the previous Q
A:
You guessed it.......
R:
Yes Delta T is leaving the building.....
etc.... etc..... etc.....
in the mean time, up a tube not to far away.... there is a hole new load of fresh cool water, waiting it's turn to get all stagnant in the block.... but there is no movement in the system... and things are getting all hot and bothered where it counts.....
then in a galaxy up in the sky there are words whispered about a thing called Turbulence........
my take on things.... optimize internals to maximize Turbulence.... all other things will miraculously fall into place.
My Motto.. Flow-rate measured, if Flow-rate wasted...
