Main Question or Discussion Point
I am unsure of where to begin to solve for my problem since I have no experience with rotating equipment. I have a 280mm rotating shaft @3000 RPM running thru a flat plate 45mm thick with a 300mm dianeter opening for the shaft. Being at sea level the one side has air pressure ratio of 1.000 while the other retains a pressure ratio of .8320. Does the rotation of the shaft create enough resistant force to prevent the environment of opposing sides from interacting with each other? Or do I assume there will be leakage fromone side to the other and ignore the forces of the rotating shaft as negligable?
