the coolant inlet temp (offset) is held at 5.0°C (±0.6) wrt the rad inlet air
coolant temp measurement resolution 0.01°C (±0.02 inst uncertainty) taken at inlet and outlet
C/W calculated using mean temp between inlet and outlet as the difference between this and the "logarithmic mean temperature difference" (normally used for heat exchanger calculations) is close to nothing for these deltaTs
note that the values are quite small
I am just observing that 'more is not necessarily better', even though that is what the theory says
and if you observe the graphs linked to it is seen thet some behave VERY differently
lots of reasons for such
I agree that few WCing systems achieve a 1.5gpm flow rate,
but the serious can do so without much difficulty
- just a LOT of attention to detail
