  I hate “delta p” so much, as in the term. I’m convinced divers just used it so they could sound even more elitist and like astronauts when they’re just dudes with a few grand and nothing better to do. Erm, akshualy that isn’t a vacuum, that’s a device that’s creates delta p. P stands for pressure and delta is a scientific notation for change. Cool dude, now finish delta p-ing your fucking room.

    Hey… Some of us just like blowing bubbles and hanging out with fish.

    It is pretty fun, but to be honest not worth the money if you have to pay for the training yourself, especially if you don’t live near a good diving spot.

      yeah, this is very true. I’d love diving tropical stuff every day but don’t want to live where it’s warm lol; where I live there are some crazy folks who drysuit dive all the time, but even then it’s waaaay too cold for me. I want the water warm but the rest nice and cool lol

        I’m one of those crazy drysuit divers. I’m usually plenty warm on a dive, and seeing a pristine shipwreck at the bottom of the great lakes is pretty awesome

    Static pressure on it’s own doesn’t really “do” anything though. You could have the thinest piece of solid material with 10 million atmospheres on either side and the material doesn’t care since forces cancel out. Difference in pressure is where shit goes pop or crush depending on the direction.

      Divers frequently go to pressures of 500+ PSI without issues directly from the pressure

      Nearly all the issues at that depth are from the physiology of breathing gasses at that pressure

        That’s 34atm or about 350m. Nobody is diving that deep. [The world record is 330m].(www.advanceddivermagazine.com/pascal.html)

      This statement is incorrect. Pressure directly affects materials. Its just without pluging the hole with a part of your body you don’t actually feel the difference. In static 10 million atmospheres stuff like metal should show some measurable shrinkage. The larger the object, the more shrinkage you will measure.

        Yes, you are technically right. Little too much hyperbole on my part, but the bulk modulus of solids in typically in the tens to hundreds of gigapascals

    You made me delta p my pants.

    Delta P isn’t a diving term. It’s an occupational safety term

  Don’t know about you, but I never take a shit without my Delta_P! Thanks Delta_P!
