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) .

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) .
