Finding the k value in a pipe flow question

  1. May 8, 2012 #1
    I am trying to do a pipe flow question but I am having trouble understanding how they have calculated the k values.
    Example question 1.1 attached & appendix A1 attached.
    We have to use appendix A1 to find the k values. I have tried using interpolation to get the k values from the example question but I am not coming up with same numbers.
    Any help would be much appreciated.

    k values are determined experimentally.
