Pressure in horizontal rotating tube

AI Thread Summary
In a horizontal rotating tube filled with an ideal gas, the pressure is higher at the free end compared to the end on the axis due to the need for centripetal force. The discussion confirms that the gas exerts a force on the tube's ends, influencing pressure distribution. The relationship between pressure and rotation is governed by the equation P.A = m.w^2.r, which highlights the role of angular velocity and radius. Participants agree on the mechanics of pressure variation in a rotating system. Understanding this principle is crucial for applications involving rotating fluids and gases.

Homework Statement


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]

Yes.
 
but will the liquid exert a force on free end of tube ??

Liquid?
I assume it's a closed tube, so yes the end of the tube will exert a force on the gas.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
