Displacement question.

[RED-DOG]

If you put Celtic into a large, (make that very large) bath and filled it with water he would float, but what would happen if you put him into a Celtic shaped bath with only a fag-paper thickness of clearance between his skin and the sides, so that you could fill the resulting gap with less than a gallon of water. Would he float then?

[kinboshi]

Dis place is mad.

[teamonkey]

no

[EvilPie]

For an object to float it has to displace water that weighs the same amount as that object.

So no.

[RED-DOG]

no

Why not?

[EvilPie]

no

Why not?

Because Archimedes says not.

[RED-DOG]

no

Why not?

Because Archimedes says not.

Is he the bloke from Nando's?

[EvilPie]

no

Why not?

Because Archimedes says not.

Is he the bloke from Nando's?

Yes that's him. The guiy who puts the sauce on the hot wings.

Is it celtic's birthday?

You do realise that if teamonkey is right, we can get a gallon of water, drown Celtic, and have have enough left over to make a cup of tea.

Evil Pie has already answered the question

for an object to float in a liquid, it has to displace the volume of liquid equal in weight to the item's own weight


so all that would happen is that celtic would get moist

and possibly a bit annoyed

and probably hungry

Your answer was much more insulting entertaining though.

I am wrong; if the bath was shaped correctly, taking into account the shape of Celtic while suspended in water, then yes, he could indeed float in a very small amount of water.

The reason for this is that his body will have effectively displaced the water by occupying the space the water would have been in.

I'm not sure of the exact minimum amount or thickness of the water layer required between Celtic and the bath wall, but I imagine theoretically he could float on less than a couple of mm of water.

He'd still get wet and cross at your experiments during his bath time

Why did he have bought a Celtic shaped bath if it wasn't to do this experiment?  Surely if he intended to have a bath, he'd just buy a normal shaped bath, albeit one that was a bit wider than the average bath.

No. He wouldn't float unless the water he displaced was heavier than he was.

Unless the bath is big enough to hold his weight in water without it spilling over the edge when he gets in, he cant float.
