Question

In a test experiment on a model aero plane in a wind tunnel , the flow speeds on the upper

and lower surfaces of the wing are 70ms

-1

and 63ms-1

respectively. What is the lift on the

wing if its area is 2.5 m

2

? Take the density of air as 1.3 kgm-3

.​​

Answer 1

Answer:

initial velocity = 70ms-¹

final velocity = 63ms-¹

area = 2.5m

density of air = 1.3 kgm-³

lift on aeroplane = ?

Explanation:

formula= S= at + 1/2at²
