Good approach

Kevin, this is an important consideration.  You do not mention it, but I assume that you would model this in a tool such as Simulink.  It is important to model the transmission lines and this can be done with CFD tools and the parameters entered into your model. 

Just as an aside, my father worked at a government lab in the last half of the last century of the last millenium.  I remember him bringing stuff home when I was a boy, and he would make cryptic comments about it.  That is all he could say.  One time he brings home a metal plate with all kinds of channels milled out.  These were made by an early CNC machine.  He made the statement that hydralics would replace electronics in many applications.  Well, I think he overstated it a bit.  But, in light of your article, I think he was on to somthing.

Hydraulics and effectiveness, and design considerations.
William K.   11/8/2013 12:13:07 PM
This article has interesting analogies with electrical systems, and they seem to be valid. I have designed mostly electrical, but also hydraulic and pneumatic systems for quite a few years. While the analogies may be useful they can also be a bit confusing. The challenges are that hydraulics can suffer from frictional losses and inertial losses, and while friction equates quite well to resistance, the inertia losses from changing directions are less obvious. Also, the pressure head developed between different levels in a hydraulic system has no real equal in electricity, I don't think. No, a few PSI head does not matter much in a 5000PSI system, but it does play a part in some return line systems.

So perhaps it would be better to just explain the hydraulics part, which the article did quite well.
