It's done differently depending on what type of flow you have. A pipe is calculated different than an airplane wing etc. Some fluid dynamicists would tell you that it's an exact science. I personally feel that it's a bit subjective. The most difficult parameter to nail down in my humble opinion is the characteristic length. It's pretty easy for pipes, you just measure the diameter... but wings, plates, vortices...get complicated quickly. You'll notice in the video I refrained from saying anything like "Flow is laminar when Reynolds number is less than XXX" or "Flow is turbulent when Reynolds number is more than XXX". There are different schools of thought on this. Typically the transition between laminar flow and turbulent flow occurs somewhere between 2100 and 4000 (Reynolds number is unitless).
