Homework Help Overview
The discussion revolves around understanding the principles of barometers and the calculations related to liquid columns in tubes. Participants are examining discrepancies in calculated values related to pressure and density.
Discussion Character
- Exploratory, Conceptual clarification, Assumption checking
Approaches and Questions Raised
- Participants are attempting to identify where calculations may have gone wrong and are encouraged to show their work. Questions about the physical principles governing liquid behavior in tubes and the relationship between pressure and height of liquid columns are raised.
Discussion Status
There is an ongoing exploration of the problem with various approaches being discussed. Some participants are questioning the application of Boyle's Law, while others are focusing on the static principles involved in the problem. Guidance has been offered to reconsider the physical relationships at play.
Contextual Notes
Participants are working with specific numerical values and assumptions about pressure and density, which may not be fully detailed in the discussion. There is an indication of differing interpretations of the problem setup.

Lets approach this from a physical point of view. What should be equal in both cases, and how does that relate to the density?

Can you relate the pressure to the height of the column of liquid in the tube?

Then construct the equation pX = pY for the two liquid columns, that is the two columns are created by the same pressure.

It has nothing to do with Boyle's law. It is actually a simple problem of statics.stuc said:
