every body out of the Pool!

watch this SUDDEN draining of a pool!

look close it happens FAST

That reminds me of some of the turbo flush toilets in hotel rooms :mrgreen:

Some engineer has got some splaining to do.

Robot narration is bad, but low-budget robot narration translation is REALLY bad! :mrgreen:

Engineering might have been fine. My first thought was if the concrete in the pool is substandard, what about the rest of the building.

First thing I thought of was when will the bottom fall out of the Xiden stock market with the same results.

So that reminds me of pools I have seen on the roofs of several hotels and condos. Yikes!!!

I'm just glad no one was in it.

Saw on the news last night that they built a "sky bridge" pool between two buildings in London that is 10 stories up in the air, and has a glass bottom for viewing. Kind of gives new meaning to "taking the plunge". Could be an eyeful for pedestrians too.

I was thinking about this and realized that if the pool had been full of people it still would have had the same weight in it........

Hmm. So if I put a container with enough water that the combined weight on a scale is ten pounds, then put a ten pound lead
weight in it and no water is spilled it won’t weigh twenty pounds?

Yea, I understand about displacement and such with regard to vessels. But if the weight and shape of the object prevents it from floating...

 

[blume357]

I was thinking about that too.... I was also thinking that if the water that was displaced did not run out the over flow then there would be more weight... now I need to try both ways...

One of the unique things I've seen like this was an elevator in Europe for lifting a boat from one canal to another.... big tank of water that the boat would go into and there was another tank with the same 'original' amount of water corresponding to it... so both tanks weigh the same regardless of if one has a boat and the other doesn't and so it takes very little energy to lift the boat up to a higher level.

Now you're talking displacement. An object in water displaces water if the water level remains the same. But that only applies to something that's floating. Sink the boat and keep the water level at the same point the water floods the space that was displaced by the hull. I haven't done displacement calcs in over forty years I'd have to dig up the formulas. Then again, they are probably somewhere on the web where you just plug in the numbers and you get the answer.

the amount displaced is the volume of the object (if it sinks)
