![b) A wing of an aircraft of 13 m span and 2.5 m mean chord is designed to develop a lift of
50 kN at a speed of 350 km/h. A 1/19 scale model of the wing section is tested in a wind
tunnel at 450 m/s and p= 5.33 kg/m³. The total drag measured is 390 N. Assuming that the
wind tunnel data refer to a section of infinite span, calculate the total drag for the full-size
wing. Assume an elliptical lift distribution and take air density as 1.2 kg/m³. Take the
coefficient of induced drag as,
