## Pump Affinity Speed Test Record

Service ID: `pump-affinity-speed-test-record`. USD 9.00 per job.

Compare measured flow with the same-impeller ideal pump speed affinity relation at homologous operating points. Fixed geometry and incompressible fluid; system-curve displacement and efficiency change are excluded. Compare the reported observedValue with calculatedValue in m3/h using the supplied nonnegative absolute tolerance; equality to tolerance passes. Calculations use finite floating point; a zero tolerance requires numerical equality. Supplied numeric evidence follows the shared twelve-significant-digit presentation policy. Supplied data and declared mathematical model only. No physical inspection, external-system change, equipment control, certification or professional approval. Unsupported nonfinite or nonexact integral profiles reject before checkout. Integral report quantities must remain exactly representable; unsupported calculation profiles reject before checkout. Use authorized, non-sensitive data. The report describes supplied records and does not change external systems.
