And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
What happens when you gravity drain liquids without venting the tank. The same thing can happen with bulk silos, vertical steel cylindrical tanks that hold dry materials used industrially. I bet this was a demonstration / test.
That's why I think it was a demonstration - I think they used a vacuum pump, like the kind you see on vacuum tankers or septic tank cleaners, to take it down so quickly and catastophically.
The instant deflation sort of illustrates how a guy feels after spending $400 on a fancy dinner, taking the gorgous lady home, putting on some mood music, feeding her a couple of Drambuies, spending some time kissing, caressing nibbling on her earlobe then peeling off her panties and she says: Sorry it's the wrong time of the month, good night.
This happened to my septic pumping guy when his safety valve failed (thankfully not at my place!). It was an epic mess. His new tanker truck has TWO safety valves. It was likely a lack-of-maintainance issue. The gif was likely a vacuum test.
I watched a guy do that to a 2,500 gallon stainless steel tank with amonia refer jacket full of the juice from Cabernet winegrapes. Idiots on forklifts.
A guy at work did that on a 6000g SS tank. Collapsed one whole side of the dome. I read about a method of using water to push it back up but was too afraid to try for fear of shoving the bottom out. Tank was on legs, not a platform.
Almost did that to a semi tanker. Was thinking about something else entirely and forgot to prop open the top hatch, and was happily standing there as the pump was pumping away for a good 5- 10 minutes before I noticed. Shut the pump off and had a hard time just opening a vent cap on the thing.
We used to fuel aircraft from 5000 gal. fuel trucks. We absolutely made sure the venting system was operational. If the vents are closed you will have a hell of a time pumping any fuel out of that truck. We had a business jet that would for no reason open the vents of the aircraft's tanks while you were fueling it - and dump fuel all over the ramp. Took forever to fix that stupid plane.
The god in question being Aeolus, the Greed Wind God? Because that was air pressure.
ReplyDeleteGreek god, not "greed god". Edit twice, post once!

ReplyDeleteSame thing can happen with water lines. That is why there's an air/vacuum release valve at the high points of the line.
DeleteThat’s under one atmosphere pressure differential. Titan submersible was at almost 400 atmospheres.
ReplyDeleteWow what a fact to think about!
DeleteThis rail-car doesnot appear to be sitting on any railroad tracks. WTF?

ReplyDeleteThe guy must've been ugly. I never had that particular circumstance happen to me.
DeleteAnd stupid. Why spend $400 when $40 will do.

I seem to recall, when this showed up everywhere, post Titan-sub-disaster, that it was attributed to a Myth Busters episode.
ReplyDeleteYeah, here's the same thing, but slower and with more drama:

ReplyDeleteAlso check the aircraft vents while fueling to keep from blowing up the fuel tanks.
DeletePrepping to scrap it.
ReplyDeleteDid that in 1980 to a brand new 3500 gallon 316 stainless steel tank for high purity sterile pharmaceutical water.
ReplyDeleteWe were steaming it out, carefully venting with nitrogen but not fast enough.
WHOOMP! We filled it with water and pushed it back into shape.
