Hello, I have a cylindrical container with a conical bottom and a hole from which a tube with a diameter of 1 cm departs. This whole system is filled with metall balls with a diameter of 1 cm, which displaces the piston. The problem is that the balls get stuck because the hole is not big enough...

it seems that yes, I cannot correctly calculate the water pressure per area, could you tell me the formula for this?

I think that on the left side of the disk has a flat surface and the pressure will push it to the right, and the right side of the disk with angles and the pressure will also be at an angle, and will not be stronger than the pressure directed straight to the right, so the disk will move, please...

Suppose the speaker has a container into which pressure is pumped, a rod passes through the container with a disk strung on it with one flat side and on the other with a pointed side, will the disk move in any direction under the influence of pressure?

1. I will assume that the pressure on the bottom after closing the valve will still become less. 2. Accordingly, with my first assumption, when opening the valve, the pressure will increase due to a column of water 3.after closing the valve in place, a certain pressure will be created and...

no, I have not encountered this, thanks for the comment from what you sent, I will study it

I mean, the pressure at the bottom of the cylinder itself, it seems to me that the pressure at the very bottom will be less because of the valve, is that so?

Imagine we have a cylinder filled with water with a closing mechanism, the height of the cylinder is quite large to create increased pressure at the very bottom. If the mechanism closes a small part at the bottom of the cylinder, will the pressure decrease or not? Thanks in advance for the answer

will the hydrostatic pressure be the same on the vessels shown with a different diameter of 1 meter and 1 centimeter? and will it be the same in both vessels if the first pipe has a diameter even less than 1 millimeter, 1 thousandth of a millimeter, 1 atom?

In the photo there are two identical containers with pipes extending from the top of the same height but at different angles, will the pressure created by the column of water differ depending on the angle of the pipe?

If you assemble the structure shown in the picture into a large container of water, lower the smaller container onto a special movable platform (red). Will the volume of displaced water be equal to the volume of the smaller container (M) according to Archimedes’ principle, or will the fact that...

If we take a surface with a strong negatively charged field and place a magnet in it in a specified position so that it does not change its angle, will the magnet be repelled and move to the side?

thanks for the reply. I thought this was possible due to the large difference in pressure at the bottom of the ocean and the usual pressure at the surface
