First you say "Except for the curvature caused by gravity," and then in the very next breath you say "Each water droplet is traveling in a straight line."If the tube had the correct curvature and was moving/rotating in the same direction and speed as the source the water droplets would travel through the curved tube.Except for the curvature caused by gravity, your curved tube wouldn't work, except to force the water into a curve. Each water droplet is traveling in a straight line. This is simple Newtonian physics, f=ma. What is your force that curves the water?
Somebody doesn't seem to know what a frame of reference is!
However, using the water source for a frame of reference, the droplets do curve.No, they appear to curve.
I fail to see the problem. We are both factoring out gravity. Without the force of gravity the water travels in a straight line.

I agreed with you that according to the revolving sources frame of reference the water appears to curve. You already agreed that measured against a stationary reference the water travels in a straight line. I am not disagreeing with you.
