Feb 23, 2023 at 17:42 comment added niels nielsen See "hydraulic analogy" on wikipedia. hydraulic impedance is system pressure divided by volume flow rate.
Feb 23, 2023 at 17:26 comment added niels nielsen impedance is the ratio of effort to flow in any dynamical system. Karnopp provides the tools to represent hydraulic systems as if they were electrical circuits. Have a look at his treatment of hydraulics. I'll see if I can find any other references which might be helpful.
Feb 23, 2023 at 12:56 comment added Fulano I found this online version of the book, and searched for the word "impedance", it showed only results related to radio and electronic systems, not hydraulics. Link: archive.org/details/systemdynamicsun0000karn/page/290/mode/…
