Talk:Displacement (fluid)

Crazy illustration
Look carefully at the illustration, which is from Carhart and Chute's 1912 physics textbook, and notice how the numbers on the graduated cylinders range from 10 (at nearly empty) to 26. The artist took liberties with the relationship between mathematics and physical reality. Can someone please find or construct a public-domain drawing that does not have this deficiency?

My first thought was to change the drawing with a simple renumbering of the existing marks on the cylinders, but I doubt that would work, because the first major mark is too close to the bottom. We'd have to replace 10 through 26 with the odd integers from 1 through 17. Snezzy (talk) 04:49, 5 November 2008 (UTC)

Fantasy-based Hypothetical Question
I am in the process of writing an urban-fantasy novel where the world's geography has changed abruptly, as has its people. Here is my hypothetical question:

Suppose that the island of Manhattan sank into the waters of the Hudson. I mean, completely, buildings and all, like an elevator going slowly down to the basement floor.

My question is: what kind of displacement effect would an event like that have on the nearby land masses? I'm not necessarily asking about tidal waves or tsunamis (though I imagine something like that would cause any number of catastrophic effects---normally; remember, this is a modern fantasy I'm writing); what I'm asking about is the effect this would have on how much land mass of the surrounding area would be consumed by the sinking of such a massive, heavy-laden island.

I appreciate any worthwhile comments (and any considerable fantasy-based ones, as well).

Thus buoyancy is expressed through Archimedes' principle, which states that the weight of the object is reduced by its volume multiplied by the density of the fluid.

density should be replaced by specific gravity (at least I hope that this is the english term for g*density: I am italian).
