| Hi Luke,
You put it out and others will develop it, in time. But I have to remind myself again and again, the real goal isn't to win an argument.
Thanks mitten, you pointed out the confusion I created. The pump’s KWH/gallon of water is most efficient at that point. Often, the proper pump is a larger pump that operates at its design point rather that one operating at an extremely low head.
You picked that up faster than most, are you an engineer?
