SUMMARY

The pressure of a liquid is solely dependent on the height of the liquid column, regardless of the container's shape. In scenarios where a sealed tank has a straw filled with water, the individual inside will experience additional pressure equivalent to the height of the water column in the straw. This principle is confirmed by various experiments demonstrating the relationship between liquid pressure and height, emphasizing the importance of atmospheric pressure in these calculations.

PREREQUISITES
  • Understanding of hydrostatic pressure principles
  • Familiarity with atmospheric pressure concepts
  • Basic knowledge of fluid dynamics
  • Experience with conducting simple physics experiments
NEXT STEPS
  • Research hydrostatic pressure calculations in fluids
  • Learn about atmospheric pressure effects on liquid columns
  • Explore fluid dynamics experiments related to pressure and height
  • Investigate the principles of vacuum and its impact on liquid behavior
USEFUL FOR

Students of physics, educators teaching fluid dynamics, and anyone interested in practical applications of pressure in liquids will benefit from this discussion.

This is just a question I have been wondering about.

From what I understand, the pressure of a liquid, no matter the shape of the container, is dependent only on height.

So, the scenario I am wondering, is:

Say I can breath underwater, and I seal myself up into a tank of ~100 gallons, so that I can fit into it (keep in mind, completely sealed, no air gaps). Now, someone cuts a tiny hole on top, say the size of a straw, and attaches a 30 foot tall straw that won't break to the hole. If they now fill that straw up all the way, will I feel like I am under 30 additional feet of water?

And, if so, would the same scenario hold similar results?

I seal myself up into an Olympic sized swimming pool. I float on the far right ride, but someone cuts a hole and adds a 100 foot straw to the left side and fills it. Do I really feel an additional 100 feet of pressure on the other side of the pool again?

Thanks

it is aptly correct that if proper vacuum is obtained and a straw of large length is filled with water then you would feel immense pressure just because of the height of the water column and the atmospheric pressure above it.it sounds a bit weird to the new learners but few experiments on variation of pressure of liquid with height confirm it.if you request further i would be able to give u list of some experiments and procedures of carrying out them in your home.

yeah, if you could, i think some of those experiments would be nice/fun :)

thanks for the answer and the verification
