Centrifuges Turn Rate Into Acceleration

Sedimentation Uses Acceleration Index

proportional only

A training sedimentation index can scale from checked acceleration. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

A training sedimentation index can use acceleration

With training factor 5, the first acceleration gives index 60.

The index scales with acceleration

The larger acceleration gives index 240. This is proportionality only, not Stokes settling.
