Vacuum in tanks similiar torricellian vacuum

[mcmpw]

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?

Welcome to PF.

... water perpetual flow or no?

No. Perpetual motion is not possible.

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.
