to reduced the back flow of water because when water comes out from the runner the pressure is lower then the atmospheric pressure due to this back flow is generated.
Yes it would. This is because the whole tube would be in the water, making the measurements the same throughout.
The draft of a ship decreases when it passes from fresh water to salt water due to the difference in density between the two types of water. Salt water is denser than fresh water, which means that a ship will experience greater buoyancy in salt water. As a result, the ship will sit higher in the water, reducing its draft. Essentially, the increased buoyant force in salt water allows the ship to displace less water, leading to a decrease in its draft.
Mosses do not have tubes for moving nutrients and water. They also do not have any true leaves, stems, or roots. Nonvascular plants also do not have transport tubes.

Clams suck in and expel water through their siphon tubes to filter food particles out of the water, to breathe (by running the water over gills), and to eliminate waste.

Not until it has been immersed for such a long time that it begins to dissolve(weeks).
Phosphorus is kept immersed in water to prevent its reaction with oxygen in the air, which can cause it to ignite spontaneously. Keeping phosphorus submerged in water helps to maintain its stability and prevent any potential hazards.
Items should be immersed in water at a temperature of at least 171F (77C) for 30 seconds for hot water sanitizing.
To be covered fully in a mass or body of water.
