SUMMARY

The discussion centers on the principles of syphons in fluid dynamics, specifically focusing on calculating the velocity of water as it exits a pipe. The primary tool referenced is Bernoulli's equation, which is applicable with certain limitations regarding intermediate height. A useful resource provided is the Wikipedia page on syphons, which offers further insights into the topic.

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?
