Question

Use the result of previous problem to design a multistage axial compressor rotating at 15,000 rpm for a mass flow rate of 65 lbm/s and pressure ratio of 4.5. The ambient condi- tion is 70°F and 14.7 psia. The degrees of reaction, work done factor, and energy trans- fer for each stage can vary although the stage efficiencies are all 90%. Keeping the mean radii constant, determine the hub and tip radij and inlet/outlet flow angles for each stage,
