Similarity in fluid mechanics

  1. May 28, 2016 #1
    1. The problem statement, all variables and given/known data
    i know that the ratio of length of prototype divided by the length of model would yield Lr

    But , some book gave that length of model divided by length of prototype also= Lr ???

    2. Relevant equations

    3. The attempt at a solution
    Which is correct ?
