Question regarding water pressure and slopes

AI Thread Summary
Two identical pressure sensors at the same ocean depth will read the same pressure, regardless of the surrounding slopes. The discussion highlights that static pressure is uniform and does not depend on the shape of the surrounding container. When considering flow through orifices, the flow rate is influenced by multiple factors beyond just pressure, including orifice design. The conversation also emphasizes the distinction between flow rate and force, clarifying that force is only relevant when the water stream impacts another surface. Overall, the principles of hydrostatics and fluid dynamics play a crucial role in understanding these scenarios.

TL;DR Summary
Questioning regarding water pressure PSI and slopes.
I have a question about water pressure PSI regarding the presents/lack of slopes.

If two identical pressure sensors are set up on the ocean floor at the same depth. One being surrounded by a cone of ramps increasing in height moving outwards away from it. The second sitting on a flat plain with no increase or decrease of the surrounding ocean floor. (I've attached an illustration for explain.) In this situation would the sensors read the same or different PSI? If different which one would be higher?

Sorry if this isn't the correct area to post in. Wasn't sure what this fit under honestly. Thanks for the help!

Welcome!
Both sensors will read the same value of pressure.

I appreciate the quick reply! Thanks for the link I believe it really cleared things up for me. It also made me relies that i forgot an important part of my question. To be honestly I'm not sure what measurement would be most appropriate for the answer of this question. I believe its head pressure but I'm not sure if I'm using it in the right context.

What if sensors 1 and 2 were replaced with twos holes of the exact same dimensions. On the other side of the hole there's a large empty container. Would the force of water coming out the other side be the same? I'm assuming they would if the static water's PSI was the same. Just i just wanted to make sure.
 
You understand that the static pressure (with nothing moving) is always the same.
The flow rate through an orifice depends upon more things than just the pressure. Our ability to describe such situations simply is very limited although it has been the subject of intense scrutiny for as long as there has been science. Now we have powerful computing machines and it is still difficult. In previous decades and centuries various specific and extraordinarilly clever approximations in fluid dynamics have been developed.
In general a more "streamlined" (a term from said fluid dynamics) orifice will produce more flow.

I can’t visualize what you describe, but Pascal’s law could be applied to that case:

It's not a force that come out, but it is quantified as flow rate, either volumetric or mass(emetric), momentum, velocity. The force comes about only when the stream contacts another surface and should not be confused with the above.

My water meter is submerged under water for about 95% of the year.

Thread 'How can I find the cleanout for my building drain?'
I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
