Same pressure points , 2 fluids u shaped tube

Click For Summary

Homework Help Overview

The discussion revolves around a U-shaped tube containing two different fluids and the pressure differences at various points within the tube. The subject area includes fluid mechanics, specifically the application of Pascal's principle.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between pressures at points A, B, C, and D, questioning whether pressures at A and B can be considered equal despite the presence of different fluids. There is an inquiry into how the system can be in balance under these conditions.

Discussion Status

Some participants have provided insights regarding the pressures at points C and D being equal, while others challenge the assumption that pressures at A and B are the same, leading to further exploration of the underlying principles.

Contextual Notes

There is an emphasis on the differences between the fluids involved and how these differences may affect pressure readings. The discussion also hints at the need for clarity regarding the setup and assumptions made in the problem.

Pressures at c and d are the same. Pressures at a and b are not the same. Do you know why?
 
Because of different fluids ?

And how the fluids are in balance if A and B pressures are not the same ?

yes
And how the fluids are in balance if A and B pressures are not the same ?
$$p_A+\rho_{left}g(x+h)=p_D$$
$$p_B+\rho_{right}g(x+h)=p_C$$
