Question 5 A 50% reaction axial air compressor rotor with an efficiency of 92% has an inlet static pressure and static temperature of 95 kPa and 56.85°C, respectively. Flow enters the rotor at a relative velocity of 285 m/s at an angle of 45°. If the outlet blade metal angle is 15°, determine: a) The outlet relative velocity. [208.6 m/s] b) The outlet static pressure. [1.13 bar] Then, if the above data were applicable to nine complete compressor stages with a stage efficiency of 88%, find: c) The blade speed. [255.1 m/s] d) The outlet static pressure and temperature. [9.01 bar; 679.4 K] e) The ratio of inlet area to outlet area. [4.61]
