Question
In the above question, the approximate fractional increase in the speed of the air on the upper surface of the wing relative to the lower surface The density of air is 
= 1.2 kg/m3 (Ignore the small height difference between the top and bottom side)
- 0.74
- 0.48
- 0.24
- 0.60
The correct answer is: 0.74
vu = velocity of upper side of aircraft
vL = velocity of lower side of aircraft
