Re: does a siphon work in vacuum?



Quoting Ludwik Kowalski <kowalskil@MAIL.MONTCLAIR.EDU>:

I also think that by changing the pressure of air
around the vessel with a liquid, such as Hg, would
have a negligible effect on the rate of syphoning.

That's true unless and until the pressure at the highest-level
point (i.e. lowest-pressure point) becomes a negative pressure
and the siphoning-rate drops to zero (or at best becomes
metastable against dropping to zero).
