It's not easy to find a cheap smoke generator. They start at about $600.

But here's one from an educational source similar to what we use:

I'll bet you'll see a lot of leakage without adding gases to

The fact that you are adding moisture constantly proves you have
a huge amount of infiltration (outside air coming in through
gaps).



You'd be better off finding and sealing them, then you can add
much less water, maybe none.



When we lived in Germany, our house was so tight that with just
normal water from breathing, cooking, and the occasional shower,
the house would fill with mold if we didn't open windows twice a
day. There is plenty of internal humidity generation if you
don't lose it all to a leaky house.



I tried walking around with IR thermometer, and check

various points. I probably don't have the technique

right. What I found was that the outside skin of the

trailer was all the same temp, and I couldn't find

much variation indoors. Some power companies offer

infrared thermographs, but I've not gone that far

to call em out.

In the old days you would get a roll of 35mm infrared film and shoot

there are infrared digital cameras these days.

No, that's not what it means. Gas volume is very temperature dependent.
This is a complete red herring.
Gas volume isn's additive. If you add 10 gal. of N2,STP and 10 gal. of
o2 you don't get 20 gal. of gas, STP.

Actually, it is.

PV=nRT

If P and T are constant (STP), V is proportional to n.

Humid air is lighter than dry air, since there are the same number (n)
of molecules and H2O (18) is lighter than N2 (28).

All olf the vapor dissolves into the room air.From there it travels
throughout your trailer finding places to hide. Your furniture probably
absorbs a lot of the water.
The air in your home does replenish from outdoors, so water goes there,
as well.

Looking at ir is going to depend on location and time of year. Best to have

Your "cheap HF gun" is going to show humidity from sweating pipes
behind drywall? Or damp insulation below a leaking window?

I have one of the non-contact thermometers with the 3 colour led to
tell if the targetted area is warmer or cooler than the reference. It
is handy - but not nearly sensitive enough.

A good thermal imaging camera will even show you poor wiring
connections or overloaded wires inside a wall

I noticed the air is pretty cool over mine. It is a swamp cooler ! I wonder
how much negative btu it taking away ?

You know exactly how many BTU's it takes to vaporize that much water.
Google heat of vaporization.

970.4 BTU/lb ~ 8000 BTU/gallon.
I just measured temp differential. It's not that much. 6-7 degrees, but
it's moving a lot of air.

Greg


I'm thinking. 8000 btu over 12 hours, about 600 btu hr ?

So true. Nothing like having a two alarm response
to your smoke test.

A couple years ago, when there was a fire near me,
I heard from my Dad, who saw it on TV. I drove to
look. Find the FD had holes in the roof, and four
aerial ladder streams going in. No smoke or steam
coming out, the fire musta been out by the time I
got there. Most FD do a good job, but this batch
on this day didn't impress me.

This one must have been earlier than when I arrived,
still some smoke:

I'm sure it is impossible to explain this, or anything else, to you. But for the benefit of others:

any gas behaves as an ideal gas if the temperature is high enough, the pressure is low enough, AND.....important........it is a single phase system.

CO2 as commonly used is a two phase system. As it is used, liquid phase converts to gaseous, maintaining a reasonably stable pressure at the given temperature. If this were not true, an air rifle could not possibly shoot accurately, and a number of other applications would be much more difficult. The highly useful property of relatively stable pressure is caused by the phase change - phase change is not part of the ideal gas equation, because it doesn't happen in an ideal gas.

The fact of a two phase system existing, such as in a CO2 tank, or anywhere you have water in liquid and gaseous phases together, indicates that temperature is low enough and pressure high enough that you cannot assume ideal gas conditions. A humidifier contains liquid water. Oops.

The highly useful property of relatively stable pressure is caused by the phase change - phase change is not part of the ideal gas equation, because it doesn't happen in an ideal gas.

You really are a dumbass. I already stated the phase change issue.


The fact of a two phase system existing, such as in a CO2 tank, or anywhere you have water in liquid and gaseous phases together, indicates that temperature is low enough and pressure high enough that you cannot assume ideal gas conditions. A humidifier contains liquid water. Oops.

Idiot. Do at least try to read. Then attempt a thought. It will be
a new experience.

FWIW, this is an excellent audio-video demonstrating the ideal gas....

Yes, in a manner that indicates you don't understand it.

Your posts are quick to insult but slow to show knowledge.

I'm pretty sure you don't actually have a clue about PV=nRT. But you could easily prove me wrong. Just solve the equation for V. See if Stormy got it right. Does 2 gallons of liquid water equal 3600 gallons of water vapor?

Unless you have kids who are high school students, I strongly suspect you'll have a little trouble converting 2 gallons to n in appropriate units and looking up R. You'll probably get T right. And you'll certainly get P wrong, based on your earlier posts.

But after that it's just arithmetic. V = nRT/P.

Show your work, including the units.

Then do it again off the steam tables and see what the difference is. 1%? 10%?

Nah, you don't know what steam tables are. You solve the ideal gas equation, and I'll look up the number off the steam table.

Wrong, of course.

The intentionally stupid irritate me. You certainly fall into that
category.

I *know* you're an idiot.

Now we know you're into the Malformed level of lying.

Work for what? I can't even read your stupid post. You're too stupid
to even use line breaks and I have no interest in chasing them down
for you.

Idiot.
