Explain Siphon Working with Energy/Bernoulli

[pras_quantum]

can someone please explain the working of a siphon by using either conservation of energy or bernoulli's theorem.? with easiness ..thanks!

The problem is that a siphon does not depend on either of those. Just the fact that liquid pressure is the same in all directions.

A siphon is a simple device that allows liquid to flow from a higher level to a lower level without the use of a pump. It works by utilizing the principles of both conservation of energy and Bernoulli's theorem.

According to the law of conservation of energy, energy cannot be created or destroyed, it can only be transferred from one form to another. In the case of a siphon, the energy of the liquid is transferred from its potential energy at the higher level to its kinetic energy as it flows down to the lower level.

Bernoulli's theorem states that as the speed of a fluid increases, its pressure decreases. This is because the total energy of the fluid, which is a combination of its potential and kinetic energy, remains constant. As the liquid flows down the siphon, its speed increases, causing a decrease in pressure at the top of the siphon and an increase in pressure at the bottom.

This pressure difference creates a suction force that pulls the liquid up and over the top of the siphon, allowing it to flow continuously from the higher level to the lower level. This process will continue until the liquid reaches the same level on both sides, at which point the siphon will stop working.

In summary, the working of a siphon is based on the transfer of energy from potential to kinetic and the principle of pressure differences according to Bernoulli's theorem. It is a simple yet effective way to move liquid without the need for external energy sources.
