Very very little. I would say nothing actually. There is no visible trend in the heat absorbed by the water relative flow rate.
However, I need an accurate flowmeter. The technique of using the in-out dT is very noisy at higher rates, and sqrt(Pd) * K factor is inaccurate at low rates and is flawed in that I am generating the k-factor from the in-out dT method. I should perhaps establish the k-factor for a given block by the bucket method.
Still, I am pretty sure there is no visible increase (or decrease) in "heat to water" vs flow or pressure drop.
Could additives make a difference? I am running only de-ionised water... unlikely.
