HYOH Podcast - Episode 49 (Start a group hang!)

[captaincoupal]

In this episode, Jonathan and Mark get a chance to talk to a bunch of folks who have experience managing group hangs in their region. A big thanks to Addam Wesneski, Stacy Adams, Kristal Bentley, and Juan Quinones, all of whom were a great help to learn the ins and outs of doing a great job hosting a group of hangers. After the interview, almost all of us decided that the fall is a great season for camping unless you live in Southern California.

After the panel discussion, Mark and Jonathan (and our new host Chris) chat with Shug about his experience carrying lighter and heavier loads, and the decisions that lead to carrying more weight for more comfort.

Finally Gresh and Spiguyver have some good and novel ideas for handling the condensation we all experience when using a bugnet or top cover in cold weather.

Show Notes:

• If you want to find a group hang in your area, click here to see the forum in hammock forums.net
• Check out Shug’s frost bib in this cool YouTube video.
• If you have a Chameleon, you can try out Dutch’s new Breathalyzer.

As always, we always invite your comments and suggestions on our Facebook page – like us there at https://www.facebook.com/hyohpodcast and join the conversation – we love the questions we have been getting for Mark and Gresh. You can listen to or subscribe to the podcast from a link on our home page online at https://www.hyohpodcast.com or give us a review on our page in iTunes. If you’d like to buy Mark and Jonathan a cup of coffee, go to https://www.hyohpodcast.com/donate to make a one-time donation, or you can donate monthly to our Patreon Campaign at https://www.patreon.com/hyohpodcast. As always, thanks so much for hanging around!

I love it when a new podcast comes out. And this ones a long one too. A lot of good info in this one.

Thanks for bringing us along in your journey thru the hammock camping world.

Bring out the new hosts to HangCon 2020 with you. You can introduce them live and in person.

I was so happy to be on. Thank you for having me.

Now we just have to get you out to the SoCal hang. Pro tip: get your livers in shape.

I just discovered this podcast. Congratulations on producing an informative and entertaining show.

Some nerding out about condensation follows:

The maximum amount of water vapor that can be absorbed by air varies with temperature. The warmer the air, the more water vapor it can absorb.

At 0° (freezing), air can absorb a maximum of 48.9 (~50) grams of water per m³ (cubic meter). At 30° (86°F), the amount of water vapor that can be absorbed by the air increases to 304 (~300) grams / m³. That is, air that is 30° warmer can absorb six times as much water. The scale is not linear, but these two temperatures represent a good range for normal conditions.

The amount of water that is actually absorbed by the air at any given time is called relative humidity. If it is 30°, and the air has absorbed 150 g/m³ of water, then relative humidity is 50%. Conversely, at 30°, if relative humidity is 50%, then the air contains 150 g/m³ of water.

Necessarily, then, as the air temperature drops, the relative humidity increases because the same amount of water is held in colder air. At some point, when the temperature drops far enough, the amount of water vapor absorbed by the air will exceed the ability of the air to absorb it. When that happens, the air becomes supersaturated with water vapor -- the relative humidity exceeds 100% -- and some of the absorbed water must precipitate out of the air in the form of condensation. The temperature at which this occurs given the weather conditions on any particular day is called the dew point.

Notice that the dew point -- when condensation forms -- depends on both temperature and relative humidity.

When outdoors, ambient air temperature is beyond our capability to control.

Relative humidity can be controlled with ventilation.

The immediate area around our bodies has much higher humidity than the ambient air surrounding us. When we breathe, we exhale air that is very hot and very humid. As soon as we exhale, our breath mixes with the cooler, less humid outside air -- this is why we can "see" your breath on a cold day; as soon as the air leaves our mouths, it cools and the water vapor condenses.

For example, if you go to bed when it is 30° and 50% humidity when the air contains 150 g/m³ of water, and the overnight temperature drops below about 17° (the dew point), then the air has become too cold to sustain all of the water vapor held in it, and some of the water vapor will precipitate out of the air. Condensation forms.

With ventilation, the wind does two things: first, it can carry away the warm air before it cools and the water vapor precipitates; and second, it can help evaporate any of the condensation that does form.

Inside an unventilated tent, or a hammock with a winter top cover, that hot, moist air that we exhale has nowhere to go, so it becomes mostly trapped inside the shelter system.

The warm, moist air inside the shelter still must obey the laws of thermodynamics, and as it interacts with the colder air outside the shelter against the walls of the shelter, the air inside the shelter cools, the water condenses, and condensation forms where the warm air inside meets the cold air outside: on the walls.

great podcast again! If you guys do a group hang, please give us plenty of time to request vacation. I need 4 to 6 months usually to get a weekend off

[Floridahanger]

Tis now the season for planning group hangs. There is some valuable info the guys brought out of us.

Take advantage of the weather and start your own group hang. If you make it, they will come.

And listen to some past shows while driving to the next group hang your doing your chores.
