What are the key principles of syphons in fluid dynamics?

Click For Summary
The discussion focuses on understanding syphons in fluid dynamics, specifically the calculation of water velocity as it exits the pipe. It highlights the relevance of Bernoulli's equation in this context, noting that it applies with certain limitations regarding intermediate height. A user shared a Wikipedia link that provides additional information on siphons and their velocity calculations. The conversation emphasizes the importance of understanding fluid dynamics principles for accurate siphon function. Overall, the thread serves as a resource for those seeking to grasp the mechanics of syphons.

Does anyone know anything about syphons in fluid dynamics? Or maybe a site that i could find info? I need to find the velocity of the water as it leaves the pipe...

It's just Bernoulli's equation, but with a limitation on the intermediate height. This looks pretty good to me.

Thanks both of you. This helps me too :-)
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
