Question
Air is streaming past a horizontal aeroplane wing such that its speed is 120 m/s over the upper surface and 90 m/s at the lower surface. If the density of air is 1.3 kg/m^{3}, find the difference in pressure between the top and bottom of the wing. If the wing is 10 m long and has an average width 2m, calculate the gross lift of the wing.

None of these
