1) A centrifugal air compressor stage was considered in ref 1. The stage is characterized by: • r2 = 0.15 m, b = 0.0145 m, r₁t = : 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 • α2 = 52°, ẞ2 = 30° • |W1t|/|W2| = 1.685 shroud b Th hub a) Compute W₁t|, |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 M₁. d) Compute T₁, T2 and T3. e) Compute the stage total-to-total efficiency. f) Compute the impeller total-to-total efficiency. 1) A centrifugal air compressor stage was considered in ref 1.
