Best way to estimate parasitic capacitance
Best way to estimate parasitic capacitance
(OP)
Hello,
I am working with an experimental system that includes many meters of tubing, a hydraulic accumulator, a few step changes, ball valves, and is driven by a peristaltic pump. I want to be able to estimate the parasitic capacitance of my system so that I can then compare that to the deliberate capacitance generated by the hydraulic accumulator. Has anyone done this before?
I suppose I could use a flow meter and measure the amount of time that it takes for the flow rate to change once the RPMs of the peristaltic pump is increased, but it seems to me that any measurements I get out of that are going to be off by a significant percent.
Any comments/suggestions would be appreciated.
Thanks!

You need something that will do transient analysis of fluid power systems. I'm not in that line, but someone else might have some ideas as to which ones they like.
