"Those convinced against their will are of the same opinion still."
Dale Carnegie
I like that quote.
Speaking of me....
Fools jump in where Angels fear to tread.
So i humbly submit the “modest” idea
that this heat transfer versus coolant flow argument
could be clarified by driving a manual transmission vehicle up and down a steady steep grade in each gear.
This would give data at different rpms and heat loads.
Even with an automatic trans there are various ways to “hold a gear.”
On downhill drives down a 4% grade you can go 60+ mph speeds with zero horsepower from the engine.
Many approaches to river bridges in hilly country are 4% grades.
Another good quote:
If you torture the data long enough it will confess to anything.
