Corrected speed
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 peripheral Mach number.
