The flow speeds of air on the lower and upper surfaces of the wing ofan aeroplane are v and `sqrt2v` respectively. A is the area of the wing and `rho` is the density of th e surrounding air. What is the force of the dynamic lift on the wing ?

In a test experiement on a model aeroplane in a wind tunnel, the flow speeds on the lower and upper surfaces of the wing are upsilon and upsilonsqrt(2) respectively. If the density of air is rho and the surface area of the wings is A, what is the dynamic lift on the wing of aeroplane.

Each of the two wings of an aeroplane has area 30m^(2) . The speed of the air on the upper and lower surfaces of theon the wing of aeroplane are 90 ms^(-1) and 70 ms^(-1) respectively. If the plane is in level flight at constant speed, find the uplift and the mass of the aeroplane. Given density of air =1.29 kg m^(-3) .

In a test experiment pn a model aeroplane in a wind tunnel, the flow speeds on the upper and lower surfaces of the wing are 70 m s^-1 and 63 m s^-1 respectively. What is the lift on the wing if its area is 2.5 m^2 ? Take the density of air to be 1.3 kg m^-3 .
