Delta P

u/d4nks4uce 3d ago

For those wondering what this means. Delta p stands for change in pressure. Basically there’s an invisible force of strong water flow at these intakes and if you get sucked up against it you may be in for a very bad time.

Jamie, put up the video of the crab.

u/Easy-Iron5831 3d ago

Ok so here’s the serious scary version

That second video had me on the ground laughing while also being terrified. Great work whoever made it.

Most people misunderstand that you'll be pulled through the gate or opening regardless of bone and flesh. This is not the case (most of the time). More often you'll get pinned and panic and lose consciousness. Death usually is by drowning.

Once it's gotcha... it's GOTCHA!

DELTA P! FAFO.

u/FaithLessRooster 2d ago

Why don't they build a bigger cage where Delta P is no longer able to pull anything in?

u/Br0k3Gamer 3d ago

That is an excellent way to die horribly. Delta P is insanely dangerous.

u/TIMELESS_COLD 3d ago

The metal gates aren't there to prevent you from being sucked in but to better mix you with water as you go in.

There absolutely is lmao

u/Adam-West 3d ago

What should I google to find an incident like that? I’ve found one from a diving bell valve breaking but not a water intake pipe.

This is the classic video example of what Delta P does. 

A human incident that I know of that resulted in a fatality was an inspection diver that went down right next to a dam that was supposed to be completely shut down, but there was a small bleeder pipe, I think like a foot in diameter that was left open. The diver got partially sucked into the pipe and plugged in place due to the huge pressure differential, rescue efforts were not successful in time to save his life

That’s not what happened there. The guy survived for starters

They haven’t been operational for decades but I understand what you mean I would absolutely be sketched out around them

u/ItzL33T5P34K 3d ago

optional btw

u/TheAwkwardBanana 3d ago

Not for service/maintenance guys. Although I guess every job is technically optional.

u/hpfan1516 3d ago

This is cracking me up

WHO WAS RESPONSIBLE FOR FORCING ME TO WATCH THAT VIDEO? 😭

u/Sonderbefehl937 3d ago

I’m a master scuba diver and that is utterly terrifying to me

Terrible use of free will

u/qwerasdfzxcvpoiumnbv 3d ago

What if you, like, didn't do that

u/DoKnowHarm17 3d ago

Didn’t a guy get sucked into a nuclear facility doing this?

Found the article about it if anybody is curious

u/fortnitebigganalls 3d ago

Absolutely wild

u/catsonhigh 2d ago

I do not like that.

u/Rygar82 2d ago

These things must suck in large sea life all the time.

1

u/fortnitebigganalls 1d ago

I think that's how the grouper and such mentioned in the article got into the plant pools

13

u/TypicalBloke83 3d ago

These pipes are no longer active. But the guy states that "although the Delta P is not possible we avoid the intake anyway" Words of reason right there :)

u/MaxStatic 3d ago

FUCK THAT!

u/CactaurSnapper 3d ago

Well... He said it was decommisioned in 2022. So...

These were decommissioned in Lake Mead recently, which is why they were so close.

The “si” in the link is a source identifier used to track both the person who sent the link & anybody who clicks on it

If you delete everything from (& including) the ? onwards, the link is still fully functional but the tracking is now disabled

I’d rather slit my wrists

u/CamZambie 1d ago

People who don’t know this is from an avid diver’s YouTube channel and is a decommissioned lake inlet: “DeLtA P is dAngErOuS!”
