Description
Return relative centrifugal acceleration from radius and RPM.
Laboratory quantities depend on sample volume, concentration basis, blank correction, geometry and calibration. A dilution, recovery fraction or signal correction evaluates a supplied measurement model without validating the assay, identifying a substance or establishing biological or clinical performance.
Return relative centrifugal acceleration from radius and RPM.
When to use this tool
Use Lab Centrifuge Radius Speed Factor when checking the stated laboratory bookkeeping, signal, sample or measurement convention.
How to use the tool and how it works
- Enter radiusMetres, rpm, gravity. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read relativeForce. Use the output convention below.
Return relative centrifugal acceleration from radius and RPM. Require radiusMetres/rpm >= 0 and gravity > 0; relativeForce = radiusMetres*(rpm*pi/30)²/gravity.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| radiusMetres | Radius Metres | Required. Finite number; minimum 0. |
| rpm | Rpm | Required. Finite number; minimum 0. |
| gravity | Gravity | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| relativeForce | Dimensionless centrifugal acceleration/gravity ratio; not force in newtons. | Required. Finite number. |

}Limitations and assumptions
- This is a dimensionless acceleration ratio, not a force in newtons; rotor geometry, equipment limits and safe operating conditions are not verified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified sample records, calibrated equipment and an appropriate validated measurement method; assess uncertainty and practical laboratory conditions independently.
