Recently it became necessary to be able to find the velocity and the rate of change of velocity along the surface at any point on the forward portion of a symmetrical airfoil at zero angle of attack. The given data consisted of values of the velocity at unequal intervals along the surface and of the first derivative of the velocity at the stagnation point.
