      The Reynolds transport theorem (RTT) isn't the most exciting topic, but it is the foundation for the control volume approach to solving fluid dynamics problems -- conservation of mass, momentum, and energy come from RTT.

    the fact that a great teacher also needs his notes to derive equation even after so many years of experience is shocking, when our teachers/professors ask us to memorize all the derivations of fluid mechanics for the final exam. its so messed up.

      Dr. Biddle cleared that out in his next lecture. Before rearranging the terms, he forgot to add and subtract (0) the limit of B in region 1 at t + dt divided by dt as dt approaches 0.

      This is needed when the velocity is not normal to the CSA. The cos theta is used to account for the component of the vector that is normal to the CSA.

      propagation of an electron wave function across a *2D* graphene film in a low frequency quantum field. Enjoy the example, and best wishes with your studies. I do amateur computational electromagnetics and a lot of my math ends up involving "2D volumes". Maybe not so useful for fluid mechanics, I understand :)
