Also the signal propagation speed in a fluid system is limited to the speed of sound in that fluid, vs ~c in electric circuits

[ssl-3]

There are limits to the propagation velocity of signals in both systems that are sometimes necessary to account for. Hydraulics tend to be slower, but it's still the same problem -- each just has different values to plug in and deal with.

Concerns about things like impedance matching and reflections are also the same.

And so on, and so forth.

Circuits are circuits.
