What will happen to the atmospheric pressure as the altitude increases?
Atmospheric pressure will decrease as altitude increases.
Why does atmospheric pressure increase with height?
The opposite is true. Atmospheric pressure decreases with altitude.
Which condition will pressure altitude be equal to true altitude?
When standard atmospheric conditions exist.
As you walk down a mountainside atmospheric pressure will what?
It will increase. Atmospheric pressure decreases with altitude and increases as you move toward sea level. At sea level, atmospheric pressure = 1.0
What decreases as altitude increases?
the air decreases or wind
Why do airplanes need to be pressurized?
Airplanes need to be pressurized because the atmospheric pressure, at such a high altitude, acts upon your body. Your body is trying to adjust to maintain equal pressure, causing your ears pop. Because your body cannot maintain equal pressure by itself, the airplane makes up for the rest of the pressure that is needed to equalize the atmospheric pressure.
Which airplane instrument is really just a barometer?
An altimeter is sensitive to atmospheric pressure and can show the altitude of the aircraft based on the change in atmospheric pressure from the aircraft ascending and descending. Likewise, a barometer, is sensitive to atmospheric pressure.
What will happen to the atmospheric pressure as the altitude increases?
Atmospheric pressure will decrease as altitude increases.
Can you use your hdd camcorder on an airplane?
Yes. Hard disk's do have some limitations of use at altitude, but those are generally related to atmospheric pressure at altitude. Since an airplane cabin is pressurized equivalent to 8000ft, the cabin of an airplane is still within the operating limits of hard drives (generally below 9500 ft). Whether or not the flight attendants will think you are a terrorist and take your camcorder is another story.
Is the air pressure in a flying airplane greater that outside the flying airplane?
In a commercial airliner flying at cruising altitude, the air pressure inside the airplane is considerably higher than the air pressure outside. The air pressure outside is too low for people to breathe comfortably, so the interior is pressurized.
Does pressure increase as you are increasing altitude?
No. Atmospheric pressure decreases as altitude increases.
Why does atmospheric pressure increase with height?
The opposite is true. Atmospheric pressure decreases with altitude.
What instrument is used is normally used to measure atmospheric pressure?
A barometer is used to measure atmospheric pressure. It can also measure altitude!
Why do airplanes need to be pressurized for passenger safety when flying high in the atmosphere?
An airliner might fly at 36,000 feet above sea level, which is a mile higher than the summit of Mount Everest. The air is so thin at this altitude that you'd pass out in 20-30 seconds from a lack of oxygen if the airplane were not pressurized. The only way to get around that is to either make passengers wear oxygen masks or pressurize the airplane so that the air is about as thick as it is on the ground. Most people aren't keen on wearing oxygen masks, so pressurization is the usual choice today.When up in the altitude, atmospheric pressure goes down. In order to breathe in that altitude the cabin has to pressurized.
What happens with altitude relative to pessure?
as altitude rises less there is less atmospheric pressure
Which condition will pressure altitude be equal to true altitude?
When standard atmospheric conditions exist.
What instrument is normally use measure atmospheric pressure?
A barometer is used to measure atmospheric pressure. It can also measure altitude!
