take it in a serial manner
if the choice of pumps is limited, pick that which you prefer
if such has a low head -> then ALL components must be selected with THAT parameter foremost
- low restriction wb
- low restriction radiator
- larger dia tubing
- NO fittings of any type
junk the Maze2 - but which of the Maze2 versions do you have ?
(it is a perfectly good wb, just not as good as some others for low head pumps)
do strive for 7lpm
avoid higher volume pumps with the same head capacity, just add heat with such
"from a block's point of view, it needs good c/w over the whole flow spectrum"
no, not really; a given system has only one flow rate
select a wb with good performance at THAT (design ?) flow rate
for example:
at 3lpm and below the Innovatek seems quite the best (of those I've tested)
at 7lpm and above the big Swiftechs seem to be superior (same qualifier)
- noting of course that the differences between the 'good' wbs are not so large
here's the latest on wb head losses (in the endless pursuit of greater accuracy):
should add the 462-UH later this week
