Above is the image of the question I want to ask. Please clarify on how the pressure coefficients of the upper and lower surfaces of an airfoil can be used, also if there is a set equation to calculate this lift coefficient.

  • $\begingroup$ The exact way to calculate was not provided. Just wanted to know how it would be calculated. @Bianfable $\endgroup$
