A) on top side is more than on lower side
B) on top side is less than on lower side
C) is same on both sides
D) is turbulent
Correct Answer: A
Solution :
The aerofils are so designed that \[{{P}_{upper\,\,side}}<{{P}_{lower\,\,side}}\] so that the aerofils get a lifting force in upward direction. According to Bernoulli's theorem, where the pressure is large, the velocity will be minimum or vice-versa. Thus, \[{{v}_{upper\,\,side}}>{{v}_{lower\,\,side}}\]You need to login to perform this action.
