Let's review physics.

Here's a question, how many RPM's does that thing do during its run? And er what would it be in MPH? haha. Seems that it would be quite a windy room if one was to stand in there while in operation, of course not really possible but ya know, if you could.
That's pretty simple to get a ballpark figure.

Keep your pencils and calculators handy. It's hard to describe formulae with just text.
As we all know, from high school physics the centrifugal force, Fc, for a uniformly rotating object is equal to m*V^2/R where m is the mass of the object, V being the tangential velocity of the object rotating along the arc of the rotation and R being the radius of the arc.
Simplifying, F = ma or Force is equal to mass times acceleration so we substitute ma for Fc to get V^2/R = a.
Also, Velocity around the circle is defined by rate of rotation times R so once again, we simplify to a = (rate of rotation in radians per sec)^2*R.
Now let's take a g-force of 1.5 g, or 1.5 * 32.2 ft/sec^2 and from looking inside the pod bay of M:S, we can guess the diameter of the centerfuge to be about 60 ft.
We plug this into the equation and get rotation rate as 1.27 radians per second. 2 * pi radians equals 1 rotation so we get a rotation rate of about 0.2 rotations per second. Or in terms of tangential velocity at the end of the centerfuge's arm, 0.2 * 30 = 6.06 ft/sec. Converting to mph, we get a tangential velocity of 4.13 mph.

I think that's reasonable. Of course, I'm pulling the equations from memory so I might have to double check them later. Also, these are just estimates and your mileage may vary. No warranites are implied or given. :lol:
Any questions? Class dismissed...
