Water boiling temperatures under hg vacuum

Something to think about for high pressure vacuum pumpers.
Just an observation of mine, I was wondering why my penis felt so warm after pumping. Of course it’s not boiling, but definitely heating up.
Heating up prior to pumping, 120 *F is hot to the touch, almost scalding. Unlikely but, It is possible to boil the blood inside your penis. This chart shows the temperature at which water boils under vacuum at sea level and lower atmospheric pressures.

Vacuum pressure does not cause liquids to heat up but it does allow them to boil at lower temperatures because there is less outside pressure holding the liquids molecules together in liquid form.

If your penis feels warmer after pumping it is because more nice warm blood is being allowed to flow into it.

I think the highest pressure I have ever heard a guy pumping at and definitely not recommended is 16”hg and according to your chart is nowhere near the temperature where it would boil.

There is a guy pumping at 30hg. He has not boiled his penis by what I know.

I don’t even think this pressure is even possible and since it would approximate conditions in outer space, your cock would basically explode.

That’s the same thing I said when I’ve read his post, but probably we both are wrong. Let me search the post if I can find it I’ll post the link.

Here you are

PEforFun - Big girth and woman’s sexual satisfaction

Achieving a perfect vacuum is not an easy thing to do and I can assure you that PEforFun came no where close to subjecting his cock to a perfect vacuum. If he did, his cock would no longer exist.

If his gauges were showing a vacuum of 14.7 psi, his gauges were wrong by a lot.

I know it was not a perfect vacuum, I think he knows too. I don’t think he was that far from 30hg, though, maybe 28hg, who knows; an industrial vacuum pump must have a fucking power, wouldn’t even thought anyone was so crazy to make his penis sucked by such a thing. Ticktickticker pumped up to 20hg, other guys said to have pumped over 20hg. No one had his penis exploding neither boiling. :)

To anyone reading this, anyway, don’t think to try these crazy things. I had one full month of ED from pumping and I went no more than 12hg.

Thank you, Marinera and gprent,

I thought it was an interesting subject. I do refrigeration work on the side. We often pull 29.9” hg (a perfect 30” hg, is impossible on earth) on tubing to make the water “boil out” of the tubing. Moisture causes refrigeration oil to break down, leading to compressor failures. I have never seen a dick boil out of this type of tubing. ;) ~

Yes it is an interesting topic. If you look at the chart, there isn’t huge difference untill you go over 25hg; and once you go past 29, any minimal increase will make a huge difference.

I think we all agree. Exposing any part of the human body to vacuum pressures created by an industrial pump shows considerable lack of good judgment.

Huh, assuming you warm up before pumping, would the vacuum not prolong the effect of the warmed up tissue?

Isn’t pressure directly related with heat?

Water boils in a vacuum because there is less pressure to “hold” the molecules together, so the transformation to steam is “easier” if you will.

Your penis expands in the pumping tube because the pressure in your body is pushing your penis into the tube, like your body blowing up a balloon, only your penis is the balloon. The inside of your penis is not under reduced pressure and as a result the effects of temperature/pressure do not apply like with water in a vacuum. If anything, the penis is under higher pressure and would be harder to raise the temperature from an outside heat source. The heat you feel is just your body temperature. (In my opinion.) ;)

edit: Sorry gprent, I somehow missed your post at the beginning and pretty much echoed it with mine. Suffices to say, I agree with you. :)

I almost feel inclined to stick a thermometer in there and test.

Almost.
