B Lift provided by a wing

  1. Mar 20, 2016 #1
    I have attached a small sheet of wood to a stand and then all of it to a scale. After that with a air supply I've made wind go through the "wing". Due to lift, the scale showed up a negative value. Knowing that value, is it possible to calculate the lift of the wing?
    Thank you

    How would you define lift? And how does what you are measuring differ from that?

    The wind must be perpendicular to the scale's measurement axis, and any wind impinging on the weighing platform must be subtracted out. The trick is getting parallel wind streamlines. Also, lift will vary with the amount of turbulence.
