Change in Internal Energy in Accelerated Gas Chambers

Click For Summary

Homework Help Overview

The discussion revolves around the change in internal energy in two toroidal gas chambers when subjected to angular acceleration. The original poster describes two insulated closed pipes containing ideal gas, with one having an adiabatic partition wall, and seeks to understand how internal energies will change as both systems experience a change in angular velocity.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants question the insulation of the torus and the viscosity of the gas, as well as whether the comparison is qualitative. The original poster expresses uncertainty about how to begin the analysis and draws an analogy to linear motion in a gas cabin.

Discussion Status

The discussion is ongoing, with participants exploring various assumptions and clarifying the problem setup. The original poster is seeking guidance on how to approach the calculation of internal energy changes.

Contextual Notes

There are mentions of ignoring viscous drag and the need for clarity on the exact wording of the problem statement. The original poster has expressed urgency in articulating the question.

Summary:: How internal energy changes in a acclerated cabin.

There are two tourus shaped insulated closed pipes containing equal amounts of ideal gas under same conditions.
B has a adiabatic partion wall.
If both are to change angular velocity by w radians per second.
How internal energies will change in both?

What are your thoughts on this so far? Is the torus insulated? Is the gas considered to have viscosity? is this supposed to be a qualitative comparison?

Sorry for hurridly writing the question .Here , w is angular acceleration of taurus w.r.t a perpendicular axis to plane of taurus through centre. Ignore viscus drag.
I need to calculate change in internal energy per second in both cases.
Not getting idea to start.
My basis of thinking is an analogous process in linear motion of a cabin of gas when the cabin gets acclerated linearly.

What is the exact word-for-word statement of this problem?
