Yes, it would. In a very similar manner to which the concrete street would break your fall.


In an identical manner, in that water doesn't compress for crap, and would almost instantly transfer the full force of the bottom of the water hitting the pavement to your body before you even hit the ground. If the water was deep enough, you could probably make it so you died from hitting the pavement while you're still just slightly above the first floor. That's where the rope, the super glue, and the piano wire come into play.

No.

You're still going to accelerate to terminal velocity. I don't know what water's terminal velocity is but it's certainly not the same as yours so you'll either hit before the water does or after it'shiat and started to disperse. Either way, you're still going insanely fast and will have a very unpleasant and abrupt stop.

Either way, you're still going insanely fast and will have a very unpleasant and abrupt stop.


Not sure you'd see the difference over the 250ish feet you'd be falling, in particular, because for it to happen in such a way for the question to be relevant, the glass would have to more or less instantly shatter and give way, or drop as a solid block of glass. Either way, that'll pretty much define the wind resistance over such a small distance. Estimate for sky divers to hit terminal velocity in generic spread position is in the 120 to 300 meter range, depending on how you do the estimate.

While not as freaky, but still pretty amazing.... roof top swimming pool 76 stories up, right next to the edge of the bldg with only a glass wall, with the HK skyline off in the distance. Hotel W in Hong Kong. Was probably the coolest pool I've been in.

What's interesting, in the basic static analysis of a problem like that, the weight of the water from the inside part of the pool is a big benefit to countering the cantilever end moment. In a practical sense though, it probably took some unusual gymnastics in the detailing, but nothing too wild.

That's where the rope, the super glue, and the piano wire come into play.

Ta-daa.


You'd get a bit of energy dispersion as the water column expands laterally, parallel to the ground, since the water column wouldn't be bounded ... but not enough to make any real difference. Essentially, this is an identical situation to being too near an underwater explosion; shockwave impact on a submerged body. The real question would be how much the wind resistance on the trip down broke up the coherent leading surface of the water column; the more discontinuous it was when it impacted, the more energy dispersion and dissipation would occur.

I do wonder what the aftermath would look like, though. The shockwave traveling back up the water column - and through the body - would likely tear apart the internal organs (lungs are especially susceptible to this). However, in typical long-fall impacts the skin tends to rupture as the buildup of internal forces basically cause the body to explode on impact. With all the hydrostatic pressure of the surrounding the body due to the water column, though, perhaps the pressure differential would be low enough to prevent this?

Either way, you're still going insanely fast and will have a very unpleasant and abrupt stop.


Probably a death sentence...but, IF the 'column' of water was a) deep enough, and b) you didn't fall right out the bottom as it dispersed into droplets with a lower terminal velocity than your body, AND c) the water landed first, partly contained, so as to form an aerated cushion rather than a liquid mass, you might have a chance.
That's not even considering the glass.

You first :)

It would actually make matters worse, since the mass of the water (at 8 lbs/gal) would be added to yours, increasing the force with which you strike the ground. You' be pretty much a mess, but a clean one.

Killahertz: shockwave impact on a submerged body.


I think this is the exact right analogy, given the distances and materials involved. I think you'd get a lot compression cuts all over the skin, rupture lungs, eyes, and ears, and just generally be a pink oozey blob of former human by a foot or too above the ground. You'd definitely have SOME of the force escape horizontally, but you're going to splat.

JackieRabbit: since the mass of the water (at 8 lbs/gal) would be added to yours, increasing the force


Morbo says, "GRAVITY DOES NOT WORK THAT WAY".

That's true if you're concerned with the force the entire mass impacts the ground with. We're interested in the force that's being put into the body inside the mass. The only thing we need an expert on is to tell us how much the water column would spread over 240ish feet, when being preceded by a layer of tempered glass to cut down drag, and how much of the force vector is redirected outwards instead of upwards. It definitely won't matters WORSE, although depending on the coherency of the column, it could make your sudden stop quite a few feet higher than you may originally anticipate.

Headso: Now that brings up a question... If you fell 24 stories inside a pillar of water also falling 24 stories would the water break your fall at all?


At all? Yes. Enough to matter in the long run, not even close. Also, I'm no physics major, but I'm pretty sure you and the water are going to fall at rather different rates. Or more specifically, the water is going to spread out in transit, a lot.

Wow, a pretty underwhelming view

Seriously, wow, a view of a roof below you, not even a nice garden or anything.

You know what would be far more entertaining? Regular pool with a glass bottom over a giant LCD screen. The screen shows arial video so it seems that you are actually flying over something interesting, not just the hotel worker's smoke break stop.


I read that as *anal* video. And yes, that would be far more entertaining.

lunchinlewis: What's interesting, in the basic static analysis of a problem like that, the weight of the water from the inside part of the pool is a big benefit to countering the cantilever end moment. In a practical sense though, it probably took some unusual gymnastics in the detailing, but nothing too wild.


Pretty sure you would want the engineers to calculate everything with NO water in the pool - it ain't full during construction.

But without water, the load on the cantilevered end is just dead load. As you fill it, the load on both ends changes. It's a weird problem and probably involves complicated integrals and crap like that. It's why I stuck with architecture and hire people to do the tough stuff.

The water is really, really heavy. Building some sort of balcony that hangs over the edge isn't an engineering marvel. Filling it with tons and tons of water (and then using glass on the bottom, no less) is.

Mr Guy: JackieRabbit: since the mass of the water (at 8 lbs/gal) would be added to yours, increasing the force

Morbo says, "GRAVITY DOES NOT WORK THAT WAY".

That's true if you're concerned with the force the entire mass impacts the ground with. We're interested in the force that's being put into the body inside the mass. The only thing we need an expert on is to tell us how much the water column would spread over 240ish feet, when being preceded by a layer of tempered glass to cut down drag, and how much of the force vector is redirected outwards instead of upwards. It definitely won't matters WORSE, although depending on the coherency of the column, it could make your sudden stop quite a few feet higher than you may originally anticipate.


Yes. Coherency, that's it.

I don't think it's really all that bad. 30x20x1.5 meters means the total water weight is 900 tons, but only about a quarter of it is actually over the edge. It will slosh around a lot, but the total shifted weight is very low- a few tons at most. I doubt you could even get much water hammer like stress on any part of the frame since the water would just slosh out.

Aquariums routinely deal with far larger water masses and more significant stresses.

It increases the force, but dissipates it simultaneously across more mass, yielding the same acceleration.

Yes. Coherency, that's it.

//engineer


This is actually in my obscure field of expertise. Assuming you could make the glass disappear or pulverize instantly (and tempered glass, if you did actually break it, would tend to do that - think "car window") and the water started falling as a plug, it would dissipate upward from the sides much more so than it would spread out. Surface tension would break the sides up into drops, which the passing airflow would slow down much more than the bulk in the middle. They would then depart upwards relative to the coherent plug, reducing the mass.

With enough drop distance, the water would dissipate completely, leaving your wet butt to go splat all by itself since you will fall faster than the water drops (I'll spare you the math). Since I very much doubt this is "enough drop distance", you'll still be inside a water plug of some size, and the shock wave impact described by others would apply.

Ok, first, fluid dynamics is not an obscure field of expertise, generally speaking or within mechanical engineering.

Second, you're correct in that turbulent mixing would occur at the boundary of the two fluids moving at different relative velocity. The mixing would entrain air into the water and likewise, and yes, surface tension would form droplets. I don't know why that's necessary to mention. Anyone familiar with atmospheric phenomenon called "rain" know this.

Third, you're wrong. There's no "shock wave" even if a significant volume of water is still intact by the time of impact. The impact of the water would be happening at low velocities in an compliant, energy absorbing environment (air). The momentum of the water and energy generated by the impact with the ground would mostly be dissipated into the direction change the water would experience hitting the ground. I'm familiar with pressure waves of high magnitude, since they happen in fire protection systems contained by steel piping and can do major damage to such a system.

Not so much when the water is contained by a gas of low density like air.

Further, even if there was some sort of noticeable pressure wave from the impact of the water, it certainly wouldn't affect a falling person's velocity. Water pressure exerts force equally on all surfaces of an object. What would happen is you would fall about as fast as you would through the air and hit the sidewalk at about the same impact speed. And you'd be wet.

No "shock wave." Just as there is no pressure wave sent back through a hose stream (garden hose or firefighter variety, take your pick, I've been on the nozzle of both) when it hits an object or when you dump water from a bucket. Just as there are non in any waterfalls.

What kind of engineering work do you do exactly?
 
2012-08-10 08:01:23 PM

Headso: Now that brings up a question... If you fell 24 stories inside a pillar of water also falling 24 stories would the water break your fall at all?


It depends on the situation:

1) If the water falls into a container then you would get a decent amount of slowing from it, it would be rather like diving into that much water from that height. In theory, survivable if you do it *JUST* right. Few people survive such falls but they normally don't know what to do, nor do most of them wish to survive it anyway.

2) If the water is uncontained it's going to do you no good, it will just splash away and the only slowing will be from the fact that it doesn't happen instantly--there won't be enough water there to matter.

3) If you're not on the surface of the water when you hit it you will be hit by all that water that was behind you.

meanmutton: Headso: Now that brings up a question... If you fell 24 stories inside a pillar of water also falling 24 stories would the water break your fall at all?

No.

You're still going to accelerate to terminal velocity. I don't know what water's terminal velocity is but it's certainly not the same as yours so you'll either hit before the water does or after it'shiat and started to disperse. Either way, you're still going insanely fast and will have a very unpleasant and abrupt stop.


If you're in the water you're going to go at it's speed regardless of your terminal velocity.

Sorry, I referring to the third point I should have been more explicit. I was assuming that a large volume of water remained intact, so that the mass would contain, or restrict at least, the relief of pressure to the sides. You would experience a shock wave, although nothing remotely like water hammer where the volume was contained. Everything you've said is correct in the context you presented it.

I've been designing equipment for the pulp and paper industry for about 35 years. You and I are talking about something the average guy (in my experience) understands very poorly, and I was trying to simplify it for the masses. I think that if you and I were talking face to face, we'd find nothing to disagree about. And, no, fluid mechanics is hardly obscure, but what I do specifically is. And almost never relevant to day to day life.
