Manometry to determine static pressure in a pipe.

Click For Summary

Discussion Overview

The discussion revolves around the use of manometry to determine static pressure in a pipe, focusing on the application of pressure measurements and the interpretation of gauge versus atmospheric pressure. Participants share their attempts at solving a related problem.

Discussion Character

  • Technical explanation, Debate/contested, Homework-related

Main Points Raised

  • One participant presents a question and their attempted solution, expressing confidence in its correctness.
  • Another participant suggests that atmospheric pressure needs to be added to a specific pressure measurement since one point is open to the atmosphere.
  • Some participants inquire about the distinction between gauge pressure and absolute pressure, indicating a potential misunderstanding or clarification needed regarding the type of pressure being discussed.

Areas of Agreement / Disagreement

There appears to be some disagreement regarding the correct interpretation of pressure measurements, particularly in relation to gauge pressure and atmospheric pressure. The discussion remains unresolved as participants have not reached a consensus.

Contextual Notes

Participants have not fully clarified the assumptions regarding the pressure measurement setup, nor have they resolved the mathematical implications of their claims.

pB needs atmospheric pressure added since A is open to the atmosphere.
 
asks for gauge pressure? but thanks for your contribution
