I think I have been ambiguous in first sentence, sorry.
I meant: manufacturers specifications 10m at zero flow, 20 l/min at zero head.
Does this change your conclusions?
Best regards
Many thanks!
Indeed, 10 meters is my estimate of friction in a coiled copper tube.
The coil discharges in open atmosphere, hence no static head is involved.
However I do not understand your reasoning behind "Depending if friction is dominant, you could do 10m at the low flow". I understand...
Hello,
I have 24V DC hobby pumps (10 meters, 20 liters/min manufacturer specifications).
I want to operate them at 12V to run them continuously at least 7 hours without overheating.
Application requires 10m head, 1.5 liters/min; want to put several pumps in series for this.
Question: how can...
