The speed of flow past the lower surface of a wing of an aeroplane is `50ms^(-1)`. What speed of flow over the upper surface will give a dynamic lift of `1000 pa`? Density of air `=1.3 kgm^(-3)`

The velocity of the wind over the surface of the wing of an aeroplane is 80ms^(-1) and under the wing 60ms^(-1) . If the area of the wing is 4m^(2) , the dynamic lift experienced by the wing is [density of air =1.3kg.m^(-3) ]

In a test experiment on a model aeroplane in a wind tunnel, the flow speeds on the upper and lower surface of the wing are 70 ms^(-1) and 63 ms^(-1) respectivley. What is the lift on the wing if its area is 2.5 m^(2) ? Take the density of air is 1.3 kg m^(-3) .

In a test experiment on a model aeroplane in a wind tunnel, the flow speeds on the upper and lower surfaces of the wing are 70ms^(-1) and 83ms^(-1) respectively. What is the lift on the wing, if its area is 2.5m^(2) ? Take the density of air to be 1.3kgm^(-3)
