At 18000 feet above sea levelthe air density is 12 that at sea level What is the atmospheric pressure at this altitude?
The atmoshperic pressure at 18,000 feet above sea level is 280 mm Hg.
Compare air at 18000 feet to air at sea level?
Air at 18000 ft is much less dense therefore making it harder for the hujman body to intake oxygen and filter it through the lungs.
Why is air dense at sea level?
The air has the weight of all the air above it pressing down on it. this compresses the air increasing its density. So air at sea level is more dense than air on the top of the mountain, since the air on the mountain top has less air above it pressing down.
Why does the balloon rise to a particular height above the ground and does not rise further?
At ground level its density is less than the air around it, so it rises, as the altitude increases air density decreases, when the density of the balloon and the air are equal it stops rising.
What is the density of air in the great plains?
The air density in any given place depends on its height above sea level and also varies from day to day due to variations in weather patterns.
What happens to the density of air as you go further below sea level altitude but in dry land?
Density always increases as altitude decreases. So the air density below sea level will be greater than the air density at sea level.
What is the air density at 12000 ft above sea level?
Density at 12,000 feet (or 3658 m), is 0.05302 lbm/ft^3 (or 0.8491 kg/m^3).
What is air density?
Air density is the mass of air per unit volume, which changes by temperature, humidity, and elevation. Changes in air density will change its pressure. At mean sea level and 20°C, air has a density of approximately 1.2 kg/m3.
Why is air pressures greatest at ground level?
It is not, air pressure is greatest at sea level. This is because the air pressure is caused by the weight of the air above you and at sea level the depth of the air column above you is at its maximum.
What is the dense of air?
At sea level, air has a density of approximately 1.2 kg/m3.
Is a Mirage the same thing as a Heat Inversion?
No, a Mirage is an illusion created by the refraction of light through air of varying density. A heat inversion is a ground level layer of warm air is trapped under a layer of warmer air, which is the opposite of the normal situation where ground level air is warmer than the air above.
What is low air density?
= What is low air density? = well, high or low are relative concepts. Normally the standard air density of the air is defined as the density of the air at 15ºC and at sea level pressure (standard conditions), what give a value of 1,225kg/m3. This way, we can talk about high or low air density related to the standard value. Air density depends on temperature and pressure. The colder the temperature the higher the density is, and the higher the height in the atmosphere the lower the density becomes. In the Everest peak, e.g., air density can be lower than 0,5. Meanwhile in the Antarctica (at sea level) the density could reach values higher than 1,5.
