Question

What conclusion do you get from the observation that a fountain of water is created at the leaking joint of pipes of the main water supply line?

Answer 1

Since water is a liquid, it applies pressure on the walls of the tubes of the main water supply channel. The creation of fountain water from the leaking tubes of the water supply pipeline shows us that water applies pressure on the walls of its vessel.

Complete answer:
The leakage at the joint pipes is due to the exerting force that creates pressure.
The pressure is connected with the liquid's weight. As we begin pouring more and more water, the pressure will be performing at the bottom part. The weight and pressure are directly proportional to each other. The pressure applied by the liquid underwater is slight, but the pressure increases as we go down at the base. The joint of pipes, as they are the root, will face more significant pressure. That leads to a crack, and there will be leakage.
We get the conclusion from the outcome that a fountain of water is formed at the leaking joint of tubes of the main water supply line that the pressure is done on the small opening of the pipe of main water supply that causes the water to move out of the pipe by the pressure and hence make a fountain.
When we see any leak in the water supply line, we can observe the water fountain from the leaking segment of the primary water line tubes. It shows that water applies pressure or force on the surfaces of water pipes so that water evolves out from the leaking joints.
Now, if the joints are leaking, it is evident that the water exerts the same pressure on the leaking joints. As the water gains an easy way out, it drops out of the pipe by the leaking points.
This simple phenomenon also can be defined by the buoyancy part. Archimedes' principle also provides a simple description for this phenomenon as the water applies pressure or force on the sidewalls of the vessel through which it passes.

Note: All liquids apply pressure on the container wall; the water fountain will get out with high force due to leakage. Water tends to apply pressure on the outside walls of the vessel or the pipe through which it is moving. As the water running through the water pipes applies the same level of pressure on the surfaces of the joints.
