deep ocean pressure question

[aljhoa]

i just dont understand if the pipe will work if it was like 10x longer why we cant just funnel the end out to 10x the size and get the same effect. but im thinking 50x to get same effect because the layer has less pressure

Look at compressibility characteristics of fluids and you will find impractical academic answer.

Lostowl,

I am not sure that we are talking about the same thing here and I don't quite understand what you mean by funneling to a greater diameter to decrease pressure. So I have included a quick schematic as an attachment of what I think you are suggesting. (I hope this works for this is my first time doing complex actions on this site).

Bear in mind that in classical hydrostatics (common language amongst hydro techs) pressure only changes in the vertical direction, with the pressure being constant in the horizontal direction. In the example all the pipes are filled with water to the top. For this simple example we should consider water as an incompressible fluid.

So what is your take on this simplistic pressure question or am I too over the top. Your answers are important for further development of a useable answer!

Best,
Yaroslav

All the same

The pressure at the bottom of all three pipes is the same. The pressure at the bottom is determined only by the amount of water above the measuring point. Changing the shape of the pipe has nothing to do with the pressure. If you have a 1 inch pipe 500 feet tall or a 10 inch pipe 500 feet tall the pressure is still the same at the bottom. Pressure is measured in pounds per square inch in the US. That means that the pressure is a measurement of the weight of the water pressing down on one square inch of water at the point where you are measuring it.
