Am I right in saying that,now, at 25c Environment Ch and 25c Coolant- Entry- T-joint there is a ~ 0.02drop in temp across the "6Tube +bits"'s DUT.
Previously (without? neoprene(inter-alia?) was ~0.06c drop
Amongst previous data(link) making some sense of Series1
Which had taken to be 0.52"ID?(cf 0.93"ID? of 3/4"Ts)
Crudely analysing in terms of Ev=(1-a)V^2/2gJCp and Ec=(Tw-Tx)/cosh[Rx*sqrt(h*Ap/kAp)]
Edit: All crap.These are the errors which should cancel if using eqi-sized "in" and "out" T-things
Have you abandoned smaller Ts?
Thought had possibilities due to better mixing(Re ^) and if equalized to 3/8"ID of tubing,possible, less disturbance of flow.
Apogee'ed brain needs time to re-acclimatize.
Possibly no difference, possibly it is jumping out of the frying-pan into the fire.
Probably best, for own sanity, to take hint from others and jump out of both..
