SUMMARY

The discussion centers on the impossibility of perpetual motion machines (PMMs) and the associated concepts of vacuum in tanks, specifically referencing Torricelli's principle. It is established that water levels in a catch tank will equalize at approximately 10 meters above the spillway, due to atmospheric pressure and the presence of a near vacuum of water vapor. The forum strictly prohibits discussions on PMMs, emphasizing the importance of adhering to scientific principles and avoiding pseudoscience.

PREREQUISITES
  • Understanding of Torricelli's Law and its implications on fluid dynamics.
  • Familiarity with atmospheric pressure and its effects on liquid columns.
  • Knowledge of the principles of vacuum and water vapor behavior.
  • Awareness of the scientific consensus against perpetual motion machines.
NEXT STEPS
  • Research the principles of Torricelli's Law in fluid dynamics.
  • Study atmospheric pressure effects on liquid columns and barometric measurements.
  • Explore the scientific reasoning behind the impossibility of perpetual motion machines.
  • Investigate the characteristics and applications of vacuums in fluid systems.
USEFUL FOR

Students of physics, engineers working with fluid dynamics, and anyone interested in understanding the limitations of energy systems and the principles governing vacuum behavior in liquids.

TL;DR
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:
