Question:-
In a centrifugal compressor, the highest mach number of leading to shockwave in the fluid flow occurs at
Option (A)
Diffuser inlet radius at
Option (B)
Diffuser outlet radius
Option(C)
Impeller inlet radius
Option(D)
Impeller outer radius
Correct Option:
(C)
Question Solution:
At the impeller inlet radius, The air is deflected through a certain angle before it passes into the radial channel on the impeller vane. If the MACH number at this point exceeds unity shock wave may be formed. The shock wave cause a rapid increases in the losses
