Homework Help: How to make an experiment to find the value of the Drag Coefficient of a Cone?

  1. Jan 11, 2012 #1
    How can I design an experiment to find the drag coefficient of a cone without knowing the force of drag that is acting on the cone? Is this even possible?

    I'm not sure what coefficient you want to find. Perhaps the k in F = kv, where v is the speed of the cone? Yes, I think you must measure F. I am thinking of a wind tunnel with the cone hanging into it. It would be attached to a pivot above the wind flow and a spring above or below the pivot would hold it in place but the spring would compress when there is a force on the cone. Maybe use a calibrated spring force scale as the spring so you can just read off the force in Newtons.
