I think that is a misunderstanding on your part, Abd.
The 'wet' in wet steam is ONLY suspended water droplets, NOT water
condensed on the inner walls of
the hose, nor water flowing along the bottom... The vapor is likely
flowing much faster than the
liquid water in the bottom of the hose, and its only those liquid
droplets that are flowing along
within the vapor that is the wet in wet steam.
Mark, you are focusing on the name of the thing rather than the
reality. For our purposes, "wet steam" is a 2-phase system in
equilibrium at the boiling point. The size of the phase regions is
not relevant.
Wet steam and even dry steam, unless the latter is above boiling,
will consense in the hose. More steam will be left with initally
(relatively) dry steam than with wet steam. Very wet steam might
condense quickly.
So? In the Rossi device, we don't see what's entering the hose. We
see, sometimes, what's coming out the end. Even if the entire flow
were entering the hose (as boiling hot water), when the hose is
emptied, as Rossi does, it would take about four minutes, as I
recall, for the hose to fill with water.
That's boiling hot water. The idea that the steam would be travelling
at much higher velocity than the water, though, doesn't seem right to
me. I did originally have an image in mind like that, but if even 5%
of the water is vaporized, the mixture is about 99% vapor by volume,
as I recall. I can't imagine that the water isn't picked up by that.
In fact, though, at that rate, the water would be flowing over a lip
where it is easily broken up and carried along as small droplets.
