At what altitude can you not start a fire?
In most national parks in the United States, campfires are prohibited above certain elevations (9,600 ft for Yosemite,10,000 ft for Ansel Adams with exceptions).
Does fire burn at high altitude?
The experimental data show that for the same burning surface area, the burning rate, radiation heat flux and flame temperature at the high altitude was lower than those at the low altitude.
Can you light a fire on Everest?
There is enough oxygen on top of Mount Everest to burn things, but there is not enough oxygen for most people to stay conscious long enough to build the fire.
Is there oxygen at 100000 feet?
The atmosphere is primarily nitrogen (78\%) with oxygen comprising 20.9 percent of the atmosphere. The atmosphere is generally considered to exist up to 100,000 feet (above this altitude the atmosphere is virtually a vacuum until reaching outer space).
What is the oxygen level at 7000 feet?
Why is There Less Oxygen at High Altitude
| Altitude (feet) | Altitude (meters) | Effective Oxygen \% |
|---|---|---|
| 6000 ft | 1829 m | 16.6 \% |
| 7000 ft | 2134 m | 16.0 \% |
| 8000 ft | 2438 m | 15.4 \% |
| 9000 ft | 2743 m | 14.8 \% |
Is Wildfire smoke worse at higher elevation?
“There is no relief as you go up in elevation or down in elevation. It is impacting the entire area.” Bird explains that in a winter inversion, cold air gets trapped on the valley floors. That trapped air is what collects all the smog, a smog that is locally produced from things like car exhaust.
Is it harder to light a fire at high altitude?
It depends on the fuel. Volatile gasses can burn at very high altitudes. Wood for example is hard to keep burning at 12,000 ft ele. Even wood that burns hot and is easy to light will go out easily in high altitudes but would burn like mad in lower elevations.
What is the maximum altitude of a rocket?
They can both reach an altitude of 3,000 feet when used with a booster. The booster in these rockets allows a second engine to be used during flight which gives the rocket more power for longer. High powered rockets of all kinds regularly reach altitudes of thousands of feet and sometimes tens of thousands of feet.
How hard is it to start a fire on a mountain?
If you’ve ever tried to start a fire (with typical wood product fuel) on a very high mountain, you’ll likely know how hard it can be to keep it going. That can be overcome with fuels that are prone As altitude increases, oxygen density decreases.
Why is it so hard to burn at high altitude?
As you rise in altitude in the earths atmosphere, O2 levels drop as the density decreases, making many of those same things harder to sustain that rapid oxidation. If you’ve ever tried to start a fire (with typical wood product fuel) on a very high mountain, you’ll likely know how hard it can be to keep it going.
How do aircraft sustain combustion at such high altitudes?
Aircraft are able to sustain combustion (also fire) inside their engines using the available oxygen to 70+K ft (see SR-71 and U-2 aircraft) Granted, they also have a ram air effect that brings the scarce O2 molecules at those altitudes into the combustion chamber, but it is still a fire – all supported by available atmospheric oxygen.
