Lift and Pressure Question (need help )

  1. Nov 30, 2005 #1
    This is the problem:

    We are given either a local velocity or local coefficient of pressure. Using one, the other can be solved. Freestream V is given.

    Now, if that Cp is the average Cp on the upper surface of a wing and that upper surface provides 3/4 of the lift, what is the coefficient of lift?

    How would I solve the integrand of the cl integral?

    I'm not sure I follow the problem as stated, but

    from your textbook (I'm sure)

    [tex]c_l=\int_{LE}^{TE}c_p dx[/tex]
