With only 5 data points dictating a trendline with a (visually) low R^2 value, even the interpolative confidence level isn't great.
If you could get any data at low RPMs (400-500RPM), it'd probably go a long way toward contributing to the shape of the curve at low RPMs![]()
In this case, I think it's close (because the rad is designed for low airflow), but in situations where a radiator can be easily airflow starved....data at very low airflow levels goes a long way toward showing the shape of the curve
Again, great review skinnee
EDIT: is it just me or are the trendlines different on the various 10CdT graphs?
