What happens to an airfoil that is curved on its bottom surface but flat on its top surface when it is forced through the air?

The air that goes around the bottom has farther to go than the air round the top, if after passing the air is to return ito its equilibrium. So the air over the bottom is "stretched" (more volume for the same amount). So its pressure is lower than the air on top. So, turning it upside down, the extra pressure below can be used to lift aeroplanes. That's a rather crude description, admittedly, of what is happening.

What is the surface area of a cylinder without a top or bottom?
2(pi)rh
What is the difference between total surface area and lateral surface area?
total surface area is all of the area. ex. for a square pyramid it would be the area of the square on the bottom and the four triangle sides lateral surface area is all the surface area EXCEPT the base. ex. for a square pyramid it would be the area of the four sides of the pyramid. the bottom square is NOT included. for a triangular prism it would be the area of the three rectangle sides, NOT the two triangular sides
Does a cylinder have a curved and flat surface?
Yes, a cylinder has both curved and flat surface. Considering a solid cylinder standing on its end, the circular base and the circular top are flat surfaces. The surface connecting the top and bottom is curved.
Is the base of a retangular pyramid also a face?
The bottom, or base of a pyramid would count as a face is you were finding out surface area.
Why is a cone not a prism?
A cone has a curved surface and only has one base (the bottom). A prism however, has two bases (the top and bottom) and has only polygonal faces. A cone also has an apex which a prism doesn't.
What is the force of lift?
The force of lift is what makes airplanes fly. It results from an effect called the Bernoulli Effect when air passes over and airfoil, a surface which is curved on the top and flat on the bottom. The air passing over the upper surface has farther to go and therefore goes faster than that passing over the lower surface. The faster-moving air causes the pressure above the airfoil to reduce, causing the wing to rise.

How is Bernoulli's principle related to airplanes?
Bernoulli showed (using water models) how flow over an airfoil (the top surface curved more than the bottom = shape of aircraft wing) lowered the pressure on the top surface, thus producing lift.

The curve on top of a wing of an airplane is?
Its called an airfoil. Its what gives the plane lift during flight. ------------------------------------------------------------------------------------------- An airfoil is the totality of the wing. There are various designs of airfoils. One such design was of a wedge shape, which is contrary to the accepted design of the curved upper surface. The basic airfoil includes the upper curved surface of the wing, the bottom flat or less curved surface of the wing, the cord thickness and total wing span. I had given a more thorough lay explanation of how lift is produced, but for some reason that explanation was removed. Go figure? My past background is as a flight instructor/mechanic/cropduster pilot.
What happens to a bubble released at the bottom of the ocean?
It becomes larger as it is rising toward the surface because there is pressure pushing on the bubble
What happens if humans consume products closer to the bottom of the food chain?
Then a smaller surface is needed to feed the same number of people.
Which part of the wing produces more lift the upper part or the lower part?
Tough question to answer as asked. In normal airfoils, the top of the airfoil is thicker and curved and it is this thicker, curved section that causes the air to speed up as it flows over it. This increase in airspeed over the top of the airfoil results in a lowering of the pressure and it is that pressure differential between the top and the bottom of the airfoil that is known as lift. However, while the shape of the top of the wing is what generates lift, the force itself is applied to the lower part of the wing, hence the airfoil rises. I guess the best answer would be to say it is produced by the upper part of the airfoil and is applied to the lower part of the airfoil. Look up Bernoulli for a more detailed discussion.

Why does a candle flame tapers at the top and bottom?
A candle structure includes a candle body and a plurality of wicks. The candle body is configured with a top and bottom surface, and an outside wall that tapers substantially inward from the top surface to the bottom surface. The plurality of wicks is configured to supply air through the gaps of standing wicks that protrude from the top surface of the candle structure. The plurality of wicks extends above the body and the wicks are aligned longitudinally. The plurality of wicks is arranged radially to taper outward toward the bottom surface of the candle body.
