Babylon 5 had a diameter of 840 meters. If the gravity was 1g, it would have to spin approximately 1.5 times per minute. How fast did it spin or what was the actual "gravity" on board? Are there any technical data available that describe the environment inside the station?
There's no technical data that I'm aware of but the show once quoted a rotation of about "60 miles an hour" which was a mistake and would only produce about 0.5g
PBS Space Time did an analysis on this question:
However, I think the PBS Space Time's calculations were a little off and they state that the station had a radius of 500m in radius.
Based on your diameter of 840 meters, a velocity of 60 miles per hour would only generate a centripetal acceleration equivalent to 0.17g and, to get to 1g would need to produce 1.46 rotations per minute and achieve a tangential velocity of 143.64 miles per hour in order to approximate 1g.
