why does air get thinner at higher altitudes

How High Hot Air Balloons Go (Legal limits and average

Hot air balloons normally fly between 1 000 and 3 000 feet in the air When balloons fly over populated areas they legally have to be flying above 1 000 feet in the air Because of the harsh conditions at higher altitudes hot air balloons normally don't surpass 3 000 feet

The Stratosphere

Air is roughly a thousand times thinner at the top of the stratosphere than it is at sea level Because of this jet aircraft and weather balloons reach their maximum operational altitudes within the stratosphere Due to the lack of vertical convection in the stratosphere materials that get into the stratosphere can stay there for long times Such is the case for the ozone-destroying

cruising altitudes for small GA aircraft

22 07 2014In still air range gets longer as you go higher and max cruise speeds at a given power setting increase up to a point but after around 7 000 to 8 000 feet the max cruise speeds are reduced (without turbocharging) because of the thinner air (less power from the engine) Also note the east/west rule for cruising altitudes (which start at 3 000 feet AGL (Above Ground Level) not 3 000 on the

10 Advantages and Disadvantages of Altitude Training

This training is practiced by athletes by staying and training in high altitudes at around 8 000 feet above sea level for several weeks This is because in high places there is less oxygen and the air is thinner and as a result the body learns to adapt to the reduced amount of oxygen

Breathing Easy at High Elevation – Mexperience

Many really good places to visit and live in Mexico are situated at high elevation—the height of the land in relation to sea level Elevations of 5 000 to 7 000 feet above sea level are not unusual for cities in Mexico's colonial heartland as well as those in the southern states of Oaxaca and Chiapas Mexico City and Guadalajara are also cities situated at altitude

What Causes Koilonychia?

Higher Altitudes Dreamstime Koilonychia can be caused by an individual's long-term residence at higher altitudes The atmospheric air an individual breathes in becomes thinner as they go up in elevation from sea level While the air technically contains the same 20 9 percent oxygen content at all elevations the lower pressure at higher elevations decreases the amount of effective oxygen an

Does altitude affect my fitness program?

Yes exercising or training in higher altitudes will affect your fitness program if you are not accustomed to that type of environment Being at higher elevations means the air is thinner drier and cooler Your heart will have to pump harder to keep up with it's energy demands your circulatory system will have to adapt to the change in elevation and you will also need to be conscious of

Why Are Airplanes Pressurized?

Human Transport at Higher Altitudes Since most large passenger jets and turbojets fly between 30 000 and 43 000 feet above sea level pressurization is required a person would remain conscious without it for less than a minute as he or she would be experiencing about 4 psi The reason why pilots and airlines are willing to take the small risk of potential depressurization at higher

Why is the air "thinner" in the mountains than at sea

As the others have mentioned the air at a certain height is compressed by the air above it You can imagine a column of air with its bottom at sea level rising to the top of the atmosphere At sea level the air is being compressed by all of th

Our bodies compensate for even this small change with faster breathing and a higher heart rate — at least until we acclimate to the thinner atmosphere And a loftier vacation spot (for example La Paz Bolivia at 11 942 feet) could bring on serious altitude sickness with insomnia nausea and swelling — but not for everyone Tibetan highlanders have no trouble living at 13 000 feet year in

Why do planes fly so high?

High altitudes have thinner air which is much kinder to the jet engines Jet engines require a constant supply air working better based on the stoichiometric ratio in layman's term air to fuel ratio In higher altitudes there is less air and so the engine needs less fuel so effectively less fuel is used In addition the lower air density makes the plane fly smoother and as such faster

But if we go higher up the air is thinner less dense and has less pressure When we go to the depths of the seas we have many atmospheres water is heavier and has way more pressure At both these levels humans cannot comforably move around they could even get injured Pressure suits can help humans withstand different pressures by protecting us from the difference around us Jet pilots

Which Layer Of The Atmosphere Do Airplanes Fly In

Aircrafts typically fly at higher altitudes because air gets thinner as planes ascend higher into the sky translating in less drag That means at higher altitudes planes can fly faster and use considerably less fuel The preferred region" in the airline industry usually begins at 35 000 feet and ends at 42 000 feet Operating at very high altitudes means that the amount of oxygen becomes
