A cambered airfoil is operating with 200N of lift. The velocity of the flow is 500m/s. Determine lift-induced drag by this camber airfoil. Correct Answer 0N

Given, Lift=200N, velocity = 500m/s. For cambered airfoil the downwash angle = 0°. Hence, there will be no downwash acting on the flow. Hence, there will be no induced drag. Hence, for any airfoil induced drag = 0N.
