Les, sums look ok.
Would think dPaQa is somewhat negligeable?

LMTD thing is more complicated than I had thought. Am wondering if it is not more useful to HE design, rather than the presentation/exploitation of test data?

[BillA]

am presently thinking so as well
unhelpful complexity, also many other factors ignored (air mass flow conversion, etc.)

have to consider the effect, not difficult with the present data
- I'll take a look at simplification (no one else is doing this anyway, so I should be sloppy too ?)

Thanks for looking.
Very possibly but have not done the sums.

Probably: as stated am happy that present format characterises a radiator.
However to satisfy the purists, Myth Busters, a true R (Wolverrine !/aoUo) should be considered
Maybe Greenman100 can give an authoritative view?.

Dunno

[BillA]

a bit more candid to describe this testing a empirical data collection rather than scientific analysis

so long as the methods are clearly described, . . . . .

Holy smokes.

This is over my head, I'll get back to you in 2 years after fluid dynamics/thermodynamics.

Perhaps dumb it down for me?

I am happy with that.
Would, perhaps, have prefer "C/W" to be with reference to coolant inlet.It is no biggy,

Still unsure whether should be a "gaggle of datums" rather than a "data collection"

Edit
ok gaggle of datums = collection of data
you are right Latin limited to Latin Today -1950s edition(Discipili picturam spectata)

[BillA]

well hey, lets redefine it
(there is a big advantage in using the inlet - for those not measuring the outlet temp)

who is using what ?
- I record inlet only when testing kits (could record the outlet if needed); inlet and outlet all else - same for wbs and rads

prefer cluster of datums, alternate is dispersion of datums (goddam buggers)
[the latin plural of -m is -a)

"Outlet + 2/3 metre of tubing" temperature - tubing is a complication and probably negligible but has be assessed before attempting system calculations

Edit maybe should be a "datum collection" or a "collection of data"

[lolito_fr]

Just reassuring myself:
dPaQa for "Original" Black Ice

105cfm 0.25"H20: 3.09w
70cfm 0.15"H20: 1.23W
40cfm 0.05"H20: 0.24w

Seems reasonable considering typical fan specs
