The discussion revolves around a horizontal tube that is rotating in a horizontal plane and filled with an ideal gas. Participants are exploring the pressure distribution within the tube, specifically questioning which end of the tube—near the axis of rotation or the free end—will experience higher pressure.
The discussion is ongoing, with participants sharing their thoughts on pressure differences and the forces involved. Some guidance has been provided regarding the interaction between the gas and the tube, but no consensus has been reached.
There is an assumption that the tube is closed, which may influence the pressure dynamics being discussed. The nature of the fluid (gas vs. liquid) is also a point of clarification among participants.

If there is a horizontal tube rotating on axis in horizontal plane. it is filled with an ideal gas , So which end will the pressure be higher ?
the end on axis?? or the free end
Homework Equations
P.A= m .w^2 .r
The Attempt at a Solution
i think the free end should have higher pressure which provides centripetal force[/B]
Liquid?jonny23 said:but will the liquid exert a force on free end of tube ??
