Concerning a pressure coefficient

  1. Sep 26, 2009 #1
    On wikipedia it says that the pressure coefficient can be written as

    [tex]C_p = 1 - (V/V_{inf})^2[/tex]

    where V is the velocity.

    So if I have given a steady velocity field, [tex]V = (v_x,v_y)[/tex], does the equation for [tex]C_p[/tex] hold for both coordinates or only the speed [tex]\sqrt{v_x^2+v_y^2}[/tex] ?

    I'm supposed to determine the largest and lowest value for C_p and I don´t know which formula to use.

    Basically I'm asking if there is such a thing as a pressure coefficient in the x-direction and a pressure coefficient in the y direction?
