Asingle stage axial compressor has a rotor velocity, u = 314 m/s, at the mean radius of 1 meter. the axial flow velocity remains constant through the stage at a value of 100 m/s. 1 = 0 degrees and 2 = 30 degrees. cp = 1 kj/kgk,  = 1.4 and r= 287 j/kgk. a) draw the velocity triangles (superimposed on each other) for the inlet and outlet of the rotor. b) what are 1 and the magnitudes of c1 and w1? c) what is c?
