'''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, '''<math>N/{\sqrt{\theta}}</math>''', can be calculated as follows:

'''<math>N/\sqrt{\theta} = N/\sqrt{T/288.15}</math>'''

Corrected Speed is often abbreviated to '''<math>Nc</math>''' or '''<math>Nr</math>''' (for Referred Speed).

So-called Non-Dimensional Speed '''<math>(N/\sqrt{T})</math>''' is proportional to Corrected Speed:

'''<math>N/\sqrt{T}= (N/\sqrt{\theta}) / \sqrt{288.15}</math>'''

Nomenclature:

*'''<math>T</math>''' Stagnation (or Total) Temperature (in Kelvin)

*'''<math>N</math>''' Real Shaft Speed

*'''<math>{\theta}</math>''' Referred Temperature

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