Just curious, I'm not transferring any gases. I was just watching the
guy fill our propane cylinder and it got me to wondering.
Here's the first situation: Let's say I have two gas cylinders of
equal size. One is filled with a gas that is liquid at room
temperature when compressed, the other is empty. The cylinders are
upright. Now the cylinders are connected with a pipe so that the gas
from the full one flows into the empty one. As the gas starts to fill
the empty cylinder it cools enough that it liquifies and rains into
the cylinder. But once the pressure equalizes the rain stops and the
end result is that both cylinders are at the same pressure but that
the originally full cylinder will have more liquid in it.
Here's the second situation: Everything is the same except the
empty cylinder is much larger than the full one, maybe ten times as
much volume. Once the pressure is equalized between the two cylinders
will the much larger cylinder now have more liquid than the smaller
one? I think it will.
Thanks,
Eric
