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. 288.15 K).

Corrected speed N / θ can be calculated as follows:

Corrected speed is often abbreviated to N c or N r (for referred speed).

So-called non-dimensional speed N / T is proportional to corrected speed:

Nomenclature:

In relative form, corrected speed, referred speed and non-dimensional speed are all measures of peripheral Mach number.
