Do you dissagree that it takes 6.5W of power to move 1200l/h to a height of 2m with a 100% effective pump?
What i find interesting is that my theoretical approach gives a power input of (6.5/28)=23% and skulemate got power input of 25% with his testing (see first page in this thread).
Skulemate
I'm glad to see that someone actually tried to measure the way you did. I presented an idea of measuring C/W a while ago that is not totally different than what you did.
(But it got shot down by BillA off course
).
