    9 inHg pressure differential when rapidly depressurized with the right humidity can cause fog/rain.

    Long story short, we made a jet fog up and 'rain' inside today. If we had some colder air to start with we could have made snow :)

    Damn! Your swamp coolers must cost a helluva lot to run!

    I bet that was something to see!

    "swamp coolers?"

    Used a couple -95's, and conditioned air thru the ACM as much as possible. We had to use aux heat the last two inches because the -95's weren\t putting out enough air.

    Evaporative Coolers=Swamp coolers

    And my goodness. I can read all the words and numbers but have next to no idea what they mean when all strung together like that.:haha:

    -95 - air cart... small jet engine that has a powerful bleed air exhaust hose, used for starting engines (on some airplanes) and pressurization

    ACM - aircraft climate module (the air conditioner)

    aux heat - really hot air, easier to pressurize with than conditioned air

    We had about 80% humidity to start with, so when we depressurized, everything had beads of water on it.

    Y'all need to try for real rain. A good heavy fog is definately a good start. Used to try to do this in the shower with really hot water then turn on the cold.

    By the way, I think it's a pretty damn cool experiment you did.

    Interesting. At work we have a turbocharger turned into a Gas Turbine Engine (sic) for testing. Use a leaf blower to start it spinning. Sounds like -95 is just a really LARGE "leaf blower"?

    @ 9" Hg delta aren't worried aboot collapsing the building? :D

    Probably so. And on that note, I pressurized again yesterday up to 17.8 inHg. It's really neat for me. I'm working on becoming "all systems" qualified, and have been working with the Enviromental guys for the past couple weeks.
