Question

Answer the following questions on the basis of your understanding of the following paragraphs and the related studied concepts.

Nilam observed an Aeroplane flying in sky. She wanted to know is basic principle, so she
discussed with her elder brother Kamlesh, he explained that, the wings of an aeroplane are designed in such a way that air above them moves faster than the air below them. When the aeroplane runs on the runway in order to take off, the pressure of air above and below changes. It is this difference in pressure which helps the aeroplane to take off. Nilam thanked him for such
explanation.

c) How does fast moving air above the wings affect air pressure?
d) Give an example other than this which shows high speed air accompanied by reduced
pressure​​

Answer 1

Bernoulli's Principle, states that pressure decreases when air moves faster. Air moves faster over the top of a wing, which results in an area of lower pressure. Meanwhile, the bottom of the wing experiences higher pressure. Camber increases the difference in air pressure between the top and bottom surfaces.
