The average radius of an axial compressor blade israv = 0.6 m and it rotates at a constant speed of 3500RPM.The axial velocity through this stageis cz = 130 m/s andthetwo rotor angles are β1 = 55 and β2 = 35 . Also assume that γ = 1.4, cp = 0.24, and T01 = 300 K.

a. Draw a velocity diagram for the compressor blade.

b. Calculate the stagnation pressure ratio p03/p01, (ηst = 1.0).

c. Calculate the pressure coefficient (Cp) for this rotor. Is blade stall likely?
