Hi Jay, we are in the same choir, it is all connected. I think the one dimensional views, say velocity only, are fine to get some calculations done, but it is healthy to be aware that there are other forces at play. This is why the calculated rarely matches the measured. My understanding of the energy is a little different to yourse, not sure which is a better model, I must look this up. In my mind, the total amount of energy stays the same always. It shifts from velocity to pressure, from kinetic to potential in a cyclical manner with the two vectors out of phase by 90 degrees I think? This seems very analagous to the propogation of Electromagnetic waves, with the Electric (Pressure) and Magnetic (Velocity) fields, again out of phase, rising and falling in strength, as one loses the other gains, thus egging each other along.
But then, I am a Heretic!
