Homework Help: Fluid resistance and speed

  1. Dec 14, 2012 #1
    Hi all, I know that for low speeds, the fluid resistance is F=kv while at high speeds, it's F= Dv^2. However, how do I ever know what is defined as a low speed and high speed? This kind of explanation is so qualitative and I think a quantitative one is better. Thanks all!
