Pascal's Principle: Valid w/o Gravity?

Click For Summary

Discussion Overview

The discussion centers on the validity of Pascal's Principle in the absence of gravity, exploring whether the principle holds true in different gravitational contexts, including deep space.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant asserts that Pascal's Principle is valid regardless of gravity, stating that the principle's assertion about pressure transmission in fluids is independent of gravitational effects.
  • Another participant suggests that gravity can interfere with demonstrations of Pascal's Principle, noting that hydrostatic pressure varies with depth on Earth.
  • A later reply expresses agreement with the initial assertion but seeks confirmation from others.

Is Pascal's Principle valid with no gravity?
 
Physics news on Phys.org
"Pascal's Principle" says that if you apply pressure to any part of a fluid, that pressure is transmitted to all parts of the fluid. That has nothing at all to do with gravity and is true whether gravity is present (on the surface of the earth, say) or not (in deep space far from any massive body).

Gravity will actually interfere with some of the nicest demonstrations of that principle because the hydrostatic pressure varies with depth on Earth.

Thanks to both of you! That is what I had thought, just wanted to make sure.
