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." Make up your mind already!My original statement did not cover gravity for simplicity. I rather think that your interjecting gravity into the equation is simply a strawman.

I fail to see the problem. We are both factoring out gravity. Without the force of gravity the water travels in a straight line.

Somebody doesn't seem to know what a frame of reference is!

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.

"I fail to see the problem. We are both factoring out gravity. Without the force of gravity the water travels in a straight line." [excerpt, bold emphasis mine]

Then why did you say "Except for the curvature caused by gravity, your curved tube wouldn't work, except to force the water into a curve."?

I think its time you took an online IQ test and disclosed the results.
