Verification of liquid pressure in u-shaped pipe

(1) The internal pressure of water is converted into the liquid level difference on both sides of the U-shaped pipe, and the greater the liquid level difference, the greater the internal pressure of water.

(2) Keep the density and depth of the liquid constant, and change the direction of the probe to make the liquid level difference on both sides of the U-shaped tube equal. It can be concluded that at the same depth, the pressure inside the liquid is equal in all directions.

(3) By controlling the density of the liquid and changing the depth, the height difference between the two sides of the U-shaped tube can be observed to increase, and it is concluded that the pressure of the liquid increases with the increase of the depth in the same liquid.

(4) If only the water in the beaker is changed into salt water, other conditions remain unchanged, the control depth remains unchanged, and the density increases when the water is changed into salt water, then the height difference of the liquid on both sides of the U-shaped tube becomes larger, which shows that the pressure of the liquid is also related to the density of the liquid.
