Just wondering as one does,
about pressures / weights
So thought process went like this ,,,,
If I have a helium generator of some sort,
and the gas is at the same temperature as the ambient
and a tube above the generator, say 100 m long tube, 1 m diameter
and at the top of the tube I had a small hole, and the bottom of the tube is open to the air,
may be put the bottom of the tube under water, to seal the gas being made,
Assuming the generator makes enough He to fill the tube,
The He rises into and fills the tube,
So what is the mass and weight of the He ?
would the pressure at the top be higher than at the bottom as the gas is rising ?
what would the pressure be ? I guess assuming same atmosphere pressure at top and bottom of the tube.
No its not home work,
many many decades since I went to school,
just a random thought
