I had in mind that you might have a different view, that's why I show you a drawing
So, maybe I can ask you:
What is the theoretical energy difference required to run the pump in "C" compared to "B"?
Is it E
= PI / (E
In "A" it should not require energy to run the pump - because there is no pump function, no mass displacement in the tube.
In "B" it obviously require energy to run the pump - because of coriolis effect due to radial mass displacement
In "C" I am not sure - If the radial mass displacement that creates the Coriolis force in the first place, is "gained" back at the bend, it means it will not require energy to displace mass (???)
No, I believe it's actually the reciprocal of your equation, such that E
x 2)/ ∏.
Your equation actually requires GREATER energy input for case C than for case B, which is contrary to your experimental results.
