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 relativ e velocity (in m/s) at the rotor exit is __________ ( accurate to one decimal
place).
