(20 points) Consider an ideal air compressor cascade, operating with T01 = 293 K, with inlet and exit blade metal angles of 50 and 33 respectively, operating at zero incidence, and inlet and exit Mach numbers of Mi = 0.66 and Me : 0.45 respectively. The pressure loss coefficient is Yp = 0.038. a. Determine the exit deviation angle. = b. Determine the blade pitch/chord ratio needed to achieve a diffusion factor of DF = 0.45.
