Question -
Answer -
Speed of wind on the upper surface of the wing,┬аV1┬а=70 m/s
Speed of wind on the lower surface of the wing,┬аV2┬а=63 m/s
Area of the wing,┬аA┬а= 2.5 m2
Density of air,┬а╧Б┬а= 1.3 kg mтАУ3
According to BernoulliтАЩs theorem, we have the relation:
Where,
P1┬а=Pressure on the upper surface of the wing
P2┬а=Pressure on the lower surface of the wing
The pressure difference between the upper and lower surfaces ofthe wing provides lift to the aeroplane.
Lift on the wing┬а
= 1512.87
= 1.51 ├Ч 103┬аN
Therefore, the lift on the wing of the aeroplane is 1.51 ├Ч 103┬аN.
