1) A centrifugal air compressor stage was considered in ref 1. The stage is characterized by: r2 = 0.15 m, b = 0.0145 m, rt = : 0.1057 m, r1h = 0.04091 m Axial inflow with po = 101,300 Pa, To = 300 K Mass flow rate of 3.064 kg/s w = 2000 s -1 Stage stagnation pressure ratio, P03/P01 Reaction, R = 0.55 = 1.7 rit 2 = 52, 2 = 30 |W1t|/|W2| = 1.685 shroud b Th hub a) Compute Wt|, |W2|, |Vr2|, |V02|, |V2], and neatly draw the velocity triangles at the impeller inlet and exit. b) Use the ETE to compute T02 and M2. c) Compute V1x, P1, and M. d) Compute T, T2 and T3. e) Compute the stage total-to-total efficiency. f) Compute the impeller total-to-total efficiency.
