Question:

Reference 12 contains in viscid theory calculations for the surface velocity distributions V(x) over an airfoil, where x is the chord wise coordinate. A typical result for small angle of attack is shown below. Use these data, plus Bernoulli’s equation, to estimate
(a) The lift coefficient; and
(b) The angle of attack if the airfoil is symmetric.
