🧪 Laboratory Centrifuge: RCF, Stokes Sedimentation, Pelleting Time and k-Factor (2D)

Top view of a laboratory rotor and a tube in the rotating frame. Set rotor speed, radius, liquid level, particle size and density and medium viscosity, and watch particles sediment outward into a pellet. Relative centrifugal force, Stokes drag in a radial field, pelleting time with RK4 integration and the k-factor, with four in-page numerical checks.
