Pressure at a given point depends only on height of surface above that point. So A, B, and D are all tied.

It is hilarious how much /sci/ in general cannot into basic hydrostatics, though. I look forward to idiots disputing me.

Stop ruining our fun, idiot. We want to laugh at all the faggots who can't into physics and you gave away the answer.

A, B, and D, assuming you mean at the central point in any given container.

You need to clarify the question with X points on the pictographs really.

>> No.5521511

>>5521494
No, the pressure is constant at any point at a fixed height. If it wasn't you would have no static solution.

>> No.5521516

>>5521465 >given point depends only on height of surface above that point

Except no. Pressure is equal at all points in the container.

The answer is C because there is much more liquid in the container.

I would imagine E, but than again, I am kinda retarded

the greater mass of water results in greater pressure on the bottom

>What is hydrostatic equilibrium?
If pressure was the same everywhere in a fluid why is the pressure much greater at the bottom of the ocean?

>> No.5521548

>>5521536
Yeah, that measures how tall they are.

What is the relation to h? Should we be taking the limit as plank's constant goes to zero?

The red lines on D indicate exactly what affects pressure at the bottom of that red line. The bottom of the container under the right line is under less pressure than the bottom of the container under the line in the centre.

gain we could divide the water into three sections. The middle section is similar to that of vessel A or B. Since the height of the fluid in section 1 or 3 is not high enough to produce the same pressure as the height of the fluid in 2, how does the pressure on the bottoms of section 1 and 3 get to be the same as that of 2 ?
The answer is that top of the container's walls in sections 1 and 3 produce a downward pressure that is equal to the fluid pressure in the middle section at the same level. If you poked a hole in the top of the container in sections 1 or 3, water would fountain upwards from the hole under pressure. From Pascal's principle, this pressure has to be that of the fluid in the middle section at the same level.

Why are we assuming fluid pressure and not just pressure?

It's the one with most weight on the smallest base obviously.
