I have watched that video 2 times weeks ago, and combined with things aerohead has said, they have given me a much better understanding of the physics involved. In my old nuclear power days the teacher would have given me a "gross conceptual error" and although my math may have been correct, the problem would have yielded me zero points toward making the grade. I'll post more here later, but I have ran a bunch of scenarios similar to Engineering Explained. My biggest grip is he constantly throws in unnecessary changes and variables. Keep everything constant so you have a better idea of what is going on. I'm working now, so like I said will post more later.
