Reynolds number - Characteristic dimension

  1. Apr 5, 2009 #1
    Are there any reference tables for what to use as the characteristic dimension of various shapes when calculating the Reynolds number?

    I am very interested in ballistics, and have done research and calculations for various ways of estimating the drag coefficient of various bullet shapes. I already have a somewhat crude approximation, but I wouldn't mind finding something better.

    This time I have chosen to use the Reynolds number as the basis to estimate drag coefficients in various flow regimes, and try to continue from there.
