I seriously need help. Please give me a sample of experimental write up on wind tunnel experiment given the necessary graphical forms applicable, introduction note, mathematical presentation,precautions and conclusion If you can give a photo of the diagram Thank you

Mmm that may be a little vague ! why don't you try and refine you requirements a little. Ie low speed or Supersonic ? Aerospace or Built enviroment ? its rather a large topic you see !

Momentum and drag experiment using wind tunnel. given the introduction, diagrams, theory behind the experiment, and calculations involved. I will be glad if someone can help Thank you
