I have designed a simple dampener. I would like to fill the chamber with oil and apply motion to the piston. With that I would like to

be apply to see the velocities in and out of the orifaces on the piston. Can this be done? Anything on any part of this would be helpful. I am attaching just a picture of it, please let me know if you need the assembly (i couldn't upload it without IE crashing). Thanks in advance
