Plz I need ur urgent Help : Wheel speed

what is the wheel speed in an axial compressor ?
for example when we say that the axial velocity remains constant and equal to the wheel speed of U = 50 m/s?
Does this refer to the rotational speed , or just a value for the axial velocity ?

Wow , many views but no answer ??
I dont hink it is a difficukt question although I didnt know it :)

That will, most likely, be the linear tip speed. It can't be rotational velocity with units of m/s.

The wheel speed of a compressor is generally the rotational speed (if memory serves me correctly). However, like Fred pointed out, it is normally not in m/s but rather radians/s. Are you taking it out of context perhaps?
