Losses when Object is moving through Pressurized Air

  1. Nov 10, 2008 #1
    I am a grad student(engineering, but not mechanical), and I have a rather difficult question for an actual design I am working on. If you have an object moving 200-300MPH in a pressurized air tunnel(5-10 psi), besides the losses due to drag, what are the losses, if any, that occur on the object. I imagine there would be some heat losses, but I am trying to find out if they would be significant.

    For an analogous problem, what losses would there be on a floating puck in an air hockey game that is moving 0.1 m/s and floating above the surface(small holes push air upwards, making the puck hover). Just the drag of the air moving across the top and around the sides?

    what kind of losses?? You already pointed out frictional losses.

    heat loss? yes, if the two things are at different temperatures. I think it ll rather heat up from viscous dissipation.
