the image above shows an inverted U-tube with the open end, O of one limb below the level, W of water in the tank, in order that water should begin to flow from the tank it is is necessary that
The U-tube is completely filled with water and that P should be higher that W
P should be lower than O and W
P should be lower than W and O should reach the botton of the table
The U-tube is completely filled with water and that P should be lower that W

The answer is D
This is because, for water to flow out of the tank through the U-tube, gravity must pull the water down the limb where point P is located. If P is lower than W, the water level in the tank, gravity will cause the water to flow down and out of the tube. Additionally, the U-tube must be completely filled with water to initiate the siphoning effect.
The setup in the image is a siphon. For a siphon to work and water to start flowing from the tank through the inverted U-tube, two main conditions must be met:
The U-tube must be completely filled with water (no air gaps), so that water can be pulled by atmospheric pressure and gravity.
The outlet end (P) must be lower than the water level (W) in the tank to create a pressure difference that drives the flow.
Correct Answer:
D. The U-tube is completely filled with water and that P should be lower than W
This ensures that gravity can pull the water down at P, which in turn pulls water up through the other side from O.
Let me know if you want a simple explanation or diagram to help visualize how a siphon works.
so the correct ans is D
