An axial compressor rotor with 50 % degree of reaction operates with an axial velocity of 200 m/s

Q. An axial compressor rotor with 50 % degree of reaction, operates with an axial velocity of 200 m/s. The absolute flow angle at the inlet of the rotor is 22^o with reference to the axial direction. If the axial velocity is assumed to remain constant through the rotor, the magnitude of the relative velocity (in m/s) at the rotor exit is 

Ans: 215.0 to 216.5
