Pressure Difference in Tank with/without Wooden Box

Click For Summary

Discussion Overview

The discussion revolves around the effects of a floating wooden box on the pressure experienced below it in a tank filled with water. Participants explore the implications of Archimedes' principle and how the presence of the box may alter pressure dynamics compared to a scenario without the box.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions whether the pressure below a floating wooden box differs from the pressure in the same tank without the box.
  • Another participant references Archimedes' principle, suggesting that the box displaces its own weight of water, maintaining the total weight of water plus the box above a given point.
  • A different participant proposes that if the box is significantly large, it could raise the water level enough to increase the pressure below it, calculated as (density*g*h), and seeks confirmation or correction of this idea.
  • Another participant agrees with the previous point, indicating a shared understanding of the implications of a larger box on pressure changes.

Areas of Agreement / Disagreement

Participants express differing views on the impact of the box's size on pressure changes, indicating that multiple competing perspectives exist regarding how pressure is affected in the presence of the box.

Contextual Notes

There are assumptions regarding the size of the box and the resulting water displacement that remain unaddressed, as well as the specific conditions under which pressure changes are evaluated.

if in a tank full of water big a wooden box floats on water then will the pressure below the box in the liquid be different from , the case , when there would be no wooden box ??

Apply Archimede's principal- the box displaces its own weight of water so the total weight of water plus box above a given point stays the same.

but if we consider a really big box which causes the water level to rise significantly , then i think that this will increase the pressure by (density*g*h) , pl. correct me if i am wrong or conform :)
 
Yep. I was about to point this out myself 'till I got to read your post.
