Fluid Mechanics, Drag Coefficient of a Cylinder

  1. Nov 27, 2011 #1
    1. The problem statement, all variables and given/known data

    Calculate the pressure drag cofficient for a cylinder using the trapezoidal and simpson's rule (assume the flow is the same on both sides of the cylinder).

    Angle (deg) Cp
    0 1
    30 0.274
    60 -1.565
    90 -1.3
    120 -1.288
    150 -1.288
    180 -1.288


    2. Relevant equations

    Cdp = 0.5 ∫ Cp cos∅ d∅


    3. The attempt at a solution

    How do we apply the given data in trapezoidal & simpson's rules?
    Which number represents the first value of the function (y)?

    I would change degree to radians. Looks like there a n=6 intervals

    f(X0)=1 and f(X6)= -1.288 for both trapezoidal and Simpson's rule

    Google if you don't know how to apply these rules. I like patrickJMT website for explanations.
