>>12176348Don't pretend to be a dumbass, I said 'dh', and didn't mention 'dt'; of course it isn't a flow rate problem. dV/dh is different for the same tube gemoetry because the horizontal cross-section of each tube differs (a vertical tube is circular, a tipped-over tube is elliptical). My intuition tells me the tipped tube will rise in height more slowly per the same volume; if I took the tilt to an extreme and almost laid the tube on its side, it would take a LOT of liquid to raise the height even a tiny bit.
