Dimensional analysis, I'm kinda lost

    1. The problem statement, all variables and given/known data



    3. The attempt at a solution

    I'm really new to this, and the professor didn't explain it well. IDK if I did that right so far, but I'm not sure what to do next. What does it mean by the units of .00256? Thanks

    Since you know this already, I will answer your question with another question.

    What is the full definition of [tex]C_d[/tex] ?

    What 2 important variables are missing to non-dimensionalize that term there?

    As your topic implies, check your units.
