Homework Help: Fluids/Aerodynamics Problem

  1. Jan 20, 2007 #1
    Not sure how to approach this problem. Seems simple. Here it is...

    An airplane is moving through still air at 60m/s. At some point on the wing, the air pressure is -1200N/m^2 gauge. If the density of air is 0.8kg/m^3, find the velocity of the flow at this point. Carefully list the assumptions you have made in your analysis. Express your answer in terms of nondimensional pressure coefficient Cp.

    I can tell you that Cp=(p-pinf)/qinf, where pinf is the free stream pressure and qinf=0.5*freestremdensity*freestreamvelociy^2.

    Any help would be much appreciated...
