and the above is why, despite the passage of 50 years, that
"Flow of Fluids through Valves, Fittings, and Pipe"
- Crane, Technical Paper No. 410
is still a reference today, in print, and as interactive software
(~$450 as I recall, I use the book @ $40)
as an experimentalist, it is most informative
EDIT:
I do know Mike, he posts on OC and OCAU as Aesik
one needs to note the intro
"the basic physics behind flow in a water cooling system"
it was written for those with no technical education - how far can a single article go
for some background the OC threads on 'turbulence' are illustrative
here are a few words by Mike (Aesik)
(and the usual misbehaving types)
