AI Thread Summary
Perpetual motion is not possible, and discussions about it are prohibited on the forum. The water levels in a tank will equalize at approximately 10 meters above the spillway, due to atmospheric pressure and the principles of a water-filled barometer. The thread was closed to adhere to forum rules against discussing perpetual motion machines (PMMs). Resources were provided to further explain the reasoning behind this policy. The conversation emphasizes the distinction between legitimate scientific inquiry and pseudoscience.

TL;DR Summary
onsidering fluid dynamics and conversion of mass.......after all tanks and lines filled with water, then opening sluice valve to "tank a", afterwards others, water perpetual flow or no?🤔

and if not, where will water levels equalize?

No. Perpetual motion is not possible.
Discussion of PM is forbidden on this site.

About 10 metres above the spillway of the catch tank. That is the height of a water-filled barometer, a column of water supported by atmospheric pressure with a near vacuum of water vapour above.

@mcmpw -- Welcome to PF. We do not allow discussion of PMMs here at PF, so your thread is now closed.

Please see these resources to help you understand why we do not waste time discussing PMMs:

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario
This has been discussed many times on PF, and will likely come up again, so the video might come handy.
