Hmmmm. I think I see now...
I think you were saying that it looked as though the increased power at higher flow rates was because the liquid was not cooling down as much, so the
average fluid temp was higher?
So the increased rad efficiency as flow increases would be clearer if the difference between the inlet and outlet fluid temp was very small (ie negligeable)?
Edit: Oops. The fact that the average fluid temp is higher for increased flow rates is one reason why the rad
is more efficient. Bleh.
So my question now: how does Bill regulate the
average fluid temp in the rad?
