(and note that my pump is big enough to ignore - not normally the case)
as the 'theory' would lead one to believe, fin sizing, spacing, etc. would necessarily be rather different
- but as the dT goes up, the whole task becomes easier
perhaps Les will run some bp thickness calcs for us ?
(my thought is for greater thickness)
chilled water is the future (for those not already there)

Ugh, help,dunno,but:
Found little influence(<10%) of temp on the "3 elements" I use to guess* Pressure drop.
Larger effect on Convection Coeff calculated with both Kryotherm and Flomerics Jet Impingement**
Some exploratory sums:
Perhaps no difference in the Temp response of the Swiftech462 and the WW
Yes, the lower Conv. Coeff. implies a thicker bp. - may haveanother look (Previously Predictions at 20c -
