Sure. I'm not advocating substituting electronics components with a similar seeming hydraulic one and then taking it literally, but rather guiding your basic intuition. The linear resistor is actually much nicer than the nonlinear orifice when it comes time to calculate. And some times the fluid model even does a better job encouraging one to pay attention to things like parasitics, which are too easy to ignore when looking at a circuit diagram without them.

Like the gate of a common FET.
