Yes, but is the difference of level existing between the "up" and
the "down" that cause the movement of water: if the "down" is at the
same level of the "up" no movement can exist, as you easily can see.

Quite obvious, but I wasn't talking about the device that first
generated the vapour, but about the fact that the vapour isn't moved
by the pressure but by the difference of pressure existing between
two sections (Bernoulli docet), particularly the boiler and the

In fact I had some strong doubts about the fact that the movement in
that section is laminar: a flow is laminar when the fluis flow in
parallel layers, with no disruption between the layers. If the vapour
fills any void is quite obvious thar there is a changement in the
direction of the layers, and so the movement of the vapour is chaotic
( the so called turbulent regime). But this is good because a
turbulent regime allow all the vapour to get in contact with the

Yes, of course: is on the top that vapour start to find the cold
temperature to change the state from vapour to liquid.
