If the term 'book smart' offended anyone.... please excuse me...<br>
perhaps the terminology has changed over the years.... was simply a reference to 'stats' and or 'equations' used for debate....<br>
<br>
As in nature...if TIME had nothing to do with all this, just as in the oceans of the world, you would not need a water pump at all to circulate water. The engine 'warmed' water would rise to the top. ...would be replaced by water from the bottom of the cooler
radiator, creating space for the warm water to rise to/escape to...cycle repeats... (regardless of where you want to start the loop heat/cold cold/heat). So 'flow control' IS relative. In Reality.... clogs DO reduce cooling. RATE (by equations) has no
effect on BTU of the exchanger. <br>
<br>
Your description of the heat transfer function is/was a definition of execution 'capability' of the device . BTU is not a measure of work, simply of energy. A relational definition. My flow comment was one of scale/size requirement to perform work in a reasonable
amount of time. We were apparently referencing different faces of the same function.

Dave makes a good point. And I made a classic error - I failed to<br>
state my assumptions. Mea culpa...<br>
<br>
It's got me curious now, though...if I had any spare time, it would be<br>
interesting to model heat transfer in a Triumph system sand see where<br>
the bottlenecks are. (My money is on plugged radiators).<br>
