Question 17 (5 points) A centrifugal compressor has an equal rise across

Question 17 (5 points) A centrifugal compressor has an equal rise across the rotor and diffuser. For an impeller tip Mach number of M2 = 1.33 (assume M2 = MT and y = 1.4), estimate the diffuser static pressure rise coefficient in the radial diffuser. Cp 1.25 2 Cp = 1.67 Cp 1.75 Cp = 0.25 Question 18 (5 points) Regarding centrifugal compressor impeller geometries, disregarding structural design issues, which impeller geometry type could operate at the highest blade tangential speed (UT)? Axial impeller geometry. Radial impeller geometry. Forward-leaning impeller geometry. Backswept impeller geometry.
