Corrected speed
Encyclopedia
Corrected Speed is the speed a component would rotate at if the inlet temperature corresponded to ambient conditions at Sea Level, on a Standard Day (i.e. 288.15K).

Corrected Speed ,, can be calculated as follows:



Corrected Speed is often abbreviated to or (for Referred Speed).

So-called Non-Dimensional Speed is proportional to Corrected Speed:



Nomenclature:
  • Stagnation (or Total) Temperature (in Kelvin)

  • Real Shaft Speed

  • Referred Temperature


In relative form, Corrected Speed, Referred Speed and Non-Dimensional Speed are all measures of peritheral Mach number.
