Crab vs. Pipe

November 2, 2005 11:58 AM

Holy Crab!We're several thousand feet down, where the pressure is about 3300 psi. The pressure inside that pipe? About zero. The crab? A goner.

Is it wrong of me that I am immediately thinking of Total Recall?

I think it's closer to what happens to the mutant alien in the last Alien movie, but Total Recall is good too.

Reminds me of a scene in a Stephen King story called The Raft.

A bunch of college kids swim out to a raft in the middle of a lake, and one of them gets sucked between the slats by some sort of hungry beastie living in the water. I read the story over 10 years ago and that thinking of that scene still gives me a visceral response. Ick.

Neat, but I have a couple of questions (and forgive me if they're grade nine science-level...I'm an ignorant arts student):

a) The pipe is underwater, where the pressure is 3300 psi. There is a hole being cut into the pipe. Wouldn't water rush into the hole and equalize the pressure?

b) Why the heck was this being videotaped?
posted by you just lost the game at 12:24 PM on November 2, 2005

A)

Yes water would rush in, but it takes an amount of time for that pressure to equalize. The hole had just been cut thus the crab was sucked in while it was equalizing. bad timing on his part.

B)

Because it's a robotic arm and saw, the operator needs to have some way to see what's happening which isn't possible often since they control these robots from the surface.
posted by Parannoyed at 12:29 PM on November 2, 2005

Water is rushing into the hole. That's why the crab got sucked in. I'm guessing the water hasn't filled the pipe either because the hole is newly made, or because there's a whole bunch of volume to fill.

Thanks, Parannoyed!
posted by you just lost the game at 12:31 PM on November 2, 2005

a) I guess the pipe hadn't filled with water yet. Looks like the crab happened to come along just after the robot had made only a small incision.

b) Obviously the whole thing is probably remote-controlled via a video-link. Maybe tapes help the engineers later on, since they can't very well go and inspect the work.

I'm thinking the poor little guy didn't *just* get sucked in, but buzzsaw played a big part in it.

Yeah that Lobster vs. Magnet tune is some of The Captain and Tenille's best early work, but are lobsters really magnetized? And if so, why do just drag magnets along the seafloor and do away with all that teduious lifting and setting traps?

I'm sure the saw was making some noticeable noise and vibration; I'm surprised the crab came that close to it while it was operating.

"In the days of diving suits--the sort that were connected to the surface by long hoses--divers sometimes experienced a dreaded phenomenon known as "the squeeze." This occurred when the surface pumps failed . . . the air would leave the suit with such violence that the hapless diver would be, all too literally, sucked up into the helmet and hosepipe. When hauled to the surface, "all that is left in the suir are his bones and some rags of flesh."

Just noticing the timing of this, that crab came along at the most inopportune time possible. It seems that the incision had just breached the pipe at the time the crab jerks towards the pipe. Otherwise, the crab would likely have been drawn towards the pipe from further off, possibly giving more time for equalizing pressure.

Still, 1.3 tons per square inch, I'm just amazed the crab's shell held on as long as it did.

I'm wishing now for a t-shirt with a picture of the crab caught halfway in the pipe with a large caption underneath that says "Imagine if it were you".

We were discussing this with a marine biologist here on campus. He said that it seemed pretty clear that the first "puff" is the actual crab flesh sucking right out of the shell; the shell crumples inward later, after appearing to stand for a moment.

And on the other end of that pipe, someone's getting one very, very, very fresh crabcake.

What's the question? I'm betting you think zero PSI is not possible because it's a perfect vacuum. What they probably meant was zero PSIG, or "PSI Gauge". It's referenced to standard atmospheric pressure, 14.7 PSI. 0 PSIG = 14.7 PSI.
posted by intermod at 7:54 PM on November 2, 2005

Also, re: poor crab, I wonder if it felt any pain in that short time. In my experience, it takes a few seconds for serious pain to kick in. Plus there are the "do low animal forms feel pain" and "what does it feel like to die" questions, which have probably been asked here already ...
