When the pressure of rock layers pressing on an aquifer from above and below squeeze earths surface?
autesian
How do you prove that high speed wind is accompanied by reduced air pressure?
This happens because when you blow air over the paper,the air pressure above the paper reduces.The air pressure below the paper remains the same.As the pressure below the paper is greater than that above the paper it pushes the paper up.The faster the air moves ,the more is the drop in pressure in that region
Which altitudes would have the lowest air pressure and why?
The highest altitudes have the lowest air pressure. Air pressure increases as altitude decreases. Above sea level is lower pressure; below sea level is higher pressure.
What keeps rock in the lower part of the mantle below their melting point?
Pressure from the thousands of miles of rock above.
What is the pressure difference between the external air and the pleural cavity when inhalation just begins?
In inspiration, intrapulmonary pressure drops 3mm/Hg below atmospheric pressure and air flows into the lungs.
What does the difference in air presssure above and below a birds wing cause?
The difference in air pressure above and below a wing causes lift. The lift creates flight. The result is that birds fly.
How does an airplane stay up in the air?
Winglift.Lift is pressure on the wing due differential air pressure below and above wing. This difference results from the difference in curvature of the wing top and bottom..
What two factors determine the amount of lift achieved by an airplane?
velocity and the difference in pressure above and below the wings
Is the pressure difference between the top of the balloon responsible for giving the hot air balloon a lift?
yes, because in this case meta center lies below the center of pressure is above. ballon moves due to difference of pressure
Why does the air pressure above an airplane wing differ from the pressure below it how is this pressure difference involved in flight?
Air pressure above the wing is relatively smaller than that below the wing because that is what generates the lift the plane needs to fly into the sky, but if it is the other way round, the lift won't be generated and the plane will remain on ground.
Where do you put the lettuce on a cheeseburger above or below the beef?
above or below, you will taste no difference.
What is the upward force acting on the wing of an airplane in flight?
It's called "lift" and is the difference in air pressure between above and below the wing.
When an airplane is flying how does the air pressure above a wing compare with that below the wing?
In flight, the air pressure above the wing is less than that below it.
Why is air pressure greater below the wing's surface?
It's not so much that the air pressure below a wing is greater as it is the pressure above it is less. The way a wing works, is the airfoil (shape of the wing) accelerates the air above the wing. Since the air is moving faster, it lowers the air pressure, resulting in a lower pressure above, and a higher(standard) pressure below, creating lift.
Is air pressure greater above the wing or below the wing?
Lower above, and greater below. That's what enables the wing to create lift.
What causes difference in ir pressure at earth's surface?
at sea level air is 14.7psi and it changes the higher you go up above sea level and below. just depends where you are
Where the pressure is greater 10m above the surface of the sea 20m below the surface of the sea?
Pressure increases the deeper you sink beneath the surface of the sea. So 20 metres below the surface has more pressure than 10 metres above the surface.
