A fully loaded boeing aircraft has a mass of 5.4 × 105 kg. Its total wing area is 500 m2 . It is in level flight with a speed of 1080 km/h. If the density of air ρ is 1.2 kg m-3 , the fractional increase in the speed of the air on the upper surface of the wing relative to the lower surface in percentage will be (g = 10 m/s2)
