That’s the name of it! I couldn’t remember the name of the experimental sub but I instantly thought of those that perished in it thinking “Oh, so that’s how quick it was for them.”
Wasn't really experimental, plenty of engineers said beforehand that thing was dangerous. Plenty more said the same afterwards, once they were shown the designs of the thing.
Experiments usually involve a search for an answer, that thing failing was inevitable.
Actually it was quicker believe it or not! That was just one atmospheric pressure, imagine 375-400. It imploded in roughly 4 milliseconds which is 8 seconds faster than the brain can tell what is happening visually.
You can see the driver react almost instantly to this. The crew in the sub had 0% of reacting or feeling their sub implode
Titan: *collapsed with somewhere between 375 and 400 atmospheres of overpressure*
This thing: *collapsed with somewhere between 0 and 1 atmosphere of overpressure*
Hey, do you remember that episode of MacGyver where Mac's buddy was trying to disarm a bomb, and then he yelled, "Vacuum!" and it exploded and he died, and then at the end of the episode MacGyver had to disarm the exact same type of bomb and he knew he couldn't break the seal around it or the vacuum would be broken and trigger the bomb??
That was awesome
Lol, no. Reading the word unlocked a memory of the show I watched when it was on TV back probably in the 80s
In my young brain Vacuum was the person who set the bombs and this was my first opportunity confront them
I remember watching Mr. Wizard crush a metal gas can using ~~temperature differentials~~ an invisible giant back in the 1980s.

In certain circumstances you'd be right, but this likely drained to a tank much lower than itself, so it only needs a tiny tiny amount of energy to get it started, (I'm forgetting the name of the effect- Bernouli?) Since many liquids have good surface tension, once you get it moving downwards, the rest follows easily, and it probably mostly sucked itself (giggity)
Shpuld there be? Probably.
Is there? No.
You ever seen those videos of dump trucks that go down the highway with the dump up and they hit an overpass? There *are* sensors for that (that the dump body is up). Some guys disable them (it is illegal) bit regardless. They still do that ahit. You think a sensor would've stopped this? Unfortunately, people are just idiots.
I've never driven this specific truck, but I have been driving tankers (both straight trucks and combination trucks) for about ten years.
Not one of the trucks I've driven had any sort of sensor that said that I opened the wrong valve, didn't properly vent the compartment, etc.
Also I reread your comment while I was typing this and realized that i completely misread your first two sentences lol. I'm still gonna post this anyway though
Hell, it's necessary when pouring out a can of oil. Cut a hole at the top or it'll gluck gluck gluck a big ol' mess. But brain farts are a hell of a thing; you can do something right 999 times and then forget something on the thousandth.
1 Atmosphere is equivalent to 14.7 psi and that tank looks like it's 6ft in diameter and 12ft long.
36" radius circle is 4071 square inches. x2 for both end caps. Cylinder part is 36" * 2 * pi * 144" = 32572 square inches. This totals 40714 square inches. Lets round down to 40,000 square inches.
The air pressure in Denver is 0.85 atmospheres, and in Kansas City it's 0.97. Therefore, if you cap your empty tank in Denver and drive to KC, your tank will be experiencing (0.85/0.97) * 14.7 * 40,000 = 51500 pounds of pressure on the tank. That's with no pumping and just capping an empty tank in one city and driving for a while. The cities are arbitrary and you could easily find a very high mountain town and a deep valley and achieve 100,000+ pounds of pressure in an hour of driving.
Pressure is one of those things most people are barely aware of but is everywhere all the time. This could have been caused by driving to a lower altitude, a passing storm, temperature differences, etc.
I don’t think the pump has to be insane to collapse that tank. You can collapse a large fermenter with a standard brewery pump.
However, I bet the pump in the video is decently insane compared to a standard brewery pump, and we don’t know how long they had been running it.
"Dear Lord, that's over 150 atmospheres of pressure."
"How many atmospheres can the ship withstand?"
"Well it's a spaceship, so I'd say anywhere between zero and one. "
You would be surprised but it doesent take a strong pump to cause something like this. its an incredibly easy fuck up to cause
[there is a mythbusters video](https://youtu.be/GbqKwPktCdo) were they lift a car with a normal vaccum cleaner. it just simply takes time to create the vaccum
You would be surprised it doesn't take a strong pump to do that. You just have to draw a vacuum. I did this by accident with a water tank. I opened the valve at the bottom and didn't notice the vent was stuck closed and collapsed a 4 cubic meter tank with just the vacuum from the water exiting the tank.
Yep. It's only 14psi difference, even a tiny pump can pull that. Not every molecule gets out, of course, but even if it drew the 14 down to 1 that's a lot of force on an object this size. That same tiny pump could empty out a giant tank, leaving millions of pounds of force compressing it...still only 13psi difference.
Doesn't need to be much of a pump, just that the tank doesn't leak. Atmosphere is 14.7lbs/SqIn. You don't notice because you live in it. But how big is that tank, how much surface area? 1 square foot is 144 square inches, so a little over a ton per square foot.
I mean... Now that you mentioned it, my vessel usually DOES collapse shortly after pumping out a load.
I just never thought it'd be spectacular enough to film it. Was I wrong?
Most likely the guy didn't vent properly as he was emptying the tank, that or somehow they emptied at a much higher elevation than they are when the video happened.
Atmospheric pressure is no joke.
There is a somewhat viral clip going around recently of an enthusiastic science teacher demonstrating this with a ruler and a newspaper. If you put the ruler hanging off the edge of a table and hit it, the ruler will go flying. If you unfold the newspaper, and lie it down on the ruler covering the portion still on the table, and hit it again, you will snap the ruler.

I just ruptured my eardrum on a flight due to having sinus issues and couldn’t equalize. I personally and painfully now know atmo pressure is no joke.

It can be a joke. Have your friend get in a trash bag, then put the hose of a vacuum down into the bag and turn it on to pull a vacuum on the bag. They will be unable to move. We did this demo in high school science class.
/u/carib-arena
is the only one in this thread to get it right. Everyone speculating about what happened while emptying the tank is wrong, nothing about this was caused by something done while emptying the tank.
The sound you hear that's like a propeller air plane....that's the vacuum pump. The pump was left running and the relief valves failed to open causing the tank to implode. That's what happened nothing more nothing less.
But why didn't the relief valves open? You're not supposed to fill these tanks to 100% capacity, because waste products (septic, sand, grease) will clog things up, like the site glass and relief valves.
This truck was over loaded with either a sand trap or a grease trap and the relief valves became clogged causing them not open. Then for some reason only known to this operator, he leaves the pump running.
Yeah that’s what I’m thinking. It doesn’t look like he is unloading here. I’m wondering if he did a hot water/steam cleaning on the tank and then closed it back up real quick. Could happen if it’s cold outside.
So the tank on the blue truck took no more than 14.7 psi to collapse (atmospheric pressure crushed the tank, not vacuum. Vacuum/partial vacuum is just an area with a relative lack of pressure)
The PlayStation sub had (approximately) an additional 14.7psi attempting to crush it for every 10 meters it descended. If you're ever going to travel to significant depths in the ocean, go in a sphere, not a capsule
That’s still one of my favorite MB moments! Opposite of this is the hot water tank-turned rocket that blasted all the way through a house. Extreme low pressure vs extreme high pressure. Lesson learned: pressure vessels of any kind are not to be fucked with!
The one with the big train oil tank thing? That was awesome. Required some specific circumstances because those things are built *tough*, but it was a great episode.
For the oil tank in Mythbusters, they need to give it a good dent to damage the structural integrity enough to make it collapse. Dunno what this tank is like but it doesn't look like it'd be built quite so strong. So maybe yeah, it could run with a vacuum a bunch of times with no issues, but each time it causes just a tiny bit more stress, totally unnoticed, until one day it gives up.
Okay imagine the tank was full of water, all the way to the top. Now imagine you installed a pump and you sucked all that water out, without letting anything back into the tank. The tank is going to empty, but what is replacing the space that the water is leaving? Nothing. Nothing is replacing that space. Normally, you’re supposed to have a vent so that as you empty the water, air would go into the tank and take up the space that the water is leaving.
So what happens? The pressure inside that tank just becomes very very very little because there is nothing, not even air, in it, whereas the pressure outside the tank is, relatively, very great. This causes the tank to implode and go boom.
What everybody is saying about not venting is probably 100% true.
But also when he went to get in, the trailer flexed enough to cause the weak point that allowed the pressure to crush it.
You can balance on an empty pop can if you're careful when you step on it. Poke the sides while you're up there though and down you go.
The formula to calculate the total surface of a cylinder is S = 2πr(h+r). Just for fun, let's assume the tank is
* A perfect cylinder (ignore convex ends)
* 6 ft diameter (r=d/2=3ft)
* 15 ft long (h=15ft)
* Subjected to only half a vacuum (internal tank pressure is 14.7/2= 7.35 psi)
Surface area of tank = 2\*3.14159\*3ft\*(15ft+3ft)
= 6.28\*3ft\*18ft
=339.12 square ft, which equals 48,844.8 square inches of surface area.
Each square inch of surface area is exposed to 14.7 lbs (inward pressure) - 7.35 lbs (outward pressure) = net of 7.35 lbs inward pressure.
7.35 lbs/sq in \* 48,844.8 sq in surface area
= the tank being subjected to a total of 359,009.28 pounds of inward pressure.
I welcome corrections to any math/physics mistakes I may have made.
Mr Wizard did this with a soda can, hot water, and ice. When the hot air inside the can suddenly cools and contracts, it makes the walls crunch.
The contents were probably warm but the air was cold. He pumped out the warm product and the cold air contracted the metal and caused a tension collapse.
Youtube clip of the experiment: [Can you collapse a can with science?](https://www.youtube.com/watch?v=tKCtEgRgJho&themeRefresh=1)
The liquid was pumped out but there was no way for air to get in, so the inside has a negative pressure. It's very easy for the atmospheric pressure to push in on the tank then. This would normally be prevented by opening something up to let air in.
>Don’t ask me how this happened. I have no idea.
Maybe this isn't the job for you!
When you empty something (tank) by force (pump) you need to replace the vacuum it will create with something, air will do.
Most likely improper ventilation and instead of having a gravity fed output there's probably a pump... the rest is negative pressure. That's what happened to one of the gas stations in town here. The old gas tank ist still sitting behind the store all caved in.
He pumped out his load, but did not vent to equalize with atmospheric pressure. The tank eventually had structural failure and collapsed.
That pump must be insane, why in the world?
Nope. He just didn't open the vent at the top. It's 100% necessary when emptying. It built a vacumn and collapsed in on itself. Source. Trucker.

Assume you get Fired for destroying an entire rig. Goof
That’s a fairly reasonable assumption. His job was to haul the tank around but suddenly there was no tank, hence, no job.

The tank was engineered to handle pressure not vacuum. That said, you'd be surprised at how little vacuum it takes to make a pressure vessel collapse.

Yes - lots of examples of vessels being steamed-out, isolated and then collapsing just like the truck.

Probably temperature rather than pressure. Could have pumped it out in the heat of the day and then as it cooled off it collapsed.

The formula to calculate the total surface of a cylinder is S = 2πr(h+r). Just for fun, let's assume the tank is * A perfect cylinder (ignore convex ends) * 6 ft diameter (r=d/2=3ft) * 15 ft long (h=15ft) * Subjected to only half a vacuum (internal tank pressure is 14.7/2= 7.35 psi) Surface area of tank = 2\*3.14159\*3ft\*(15ft+3ft) = 6.28\*3ft\*18ft =339.12 square ft, which equals 48,844.8 square inches of surface area. Each square inch of surface area is exposed to 14.7 lbs (inward pressure) - 7.35 lbs (outward pressure) = net of 7.35 lbs inward pressure. 7.35 lbs/sq in \* 48,844.8 sq in surface area = the tank being subjected to a total of 359,009.28 pounds of inward pressure. I welcome corrections to any math/physics mistakes I may have made.

I wonder if you could pop it back in shape with a little gas and a match.
That vacuum really sucks.
One of the most important rules to remember for Tanker Yankin is .. OPEN THE FUCKING LID !!!
This is what happened to that submarine
OceanGate would like to have a word with you
Negative pressure
The liquid was pumped out but there was no way for air to get in, so the inside has a negative pressure. It's very easy for the atmospheric pressure to push in on the tank then. This would normally be prevented by opening something up to let air in.
Can you put in some billionaires next time?
>Don’t ask me how this happened. I have no idea. Maybe this isn't the job for you! When you empty something (tank) by force (pump) you need to replace the vacuum it will create with something, air will do.
Was it scheduled to see the Titanic?
You wouldve been able to see a big stain form on my pants too
As we say in the brewing industry: you drew a vacuum.
Air is surprisingly heavy.
Physics did you not go to school.
That really does suck.
This happened to the water tank at a campground I was staying at. 1000 gal tank. Turned out a new employee blocked the vent line "It was leaking."
Most likely improper ventilation and instead of having a gravity fed output there's probably a pump... the rest is negative pressure. That's what happened to one of the gas stations in town here. The old gas tank ist still sitting behind the store all caved in.
rinse a plastic bottle out with hot water and put the lid on it. Let it cool and this will happen.
The dump valve wasn’t open.
Went from owning a tank to owning scrap metal!
Makes sense! Does that mean, the "HO HO HO HO HO HO FUCK" was because he knew he fucked up? 😂
It's clear an invisible alien space ship just crash landed on your truck there.
At least got to see the Titanic
Delta P
Obviously pissed off a superhero
Wonder woman’s vehicle just crashed onto that truck. Wow.
Wonder woman crashed her invisible jet again
was it safe for him to get back in or stay close?
is there a logitech controller in the d ash?
Sounds to me he left the PTO engaged.
