Question 2b: A one stage axial compressor (Rotor + Stator) takes in air from conditions at static pressure P1= 87.3 kPa, stagnation pressure and temperature Po1= 101.3 kPa & To1=278 K. At compressor inlet the absolute flow angle 30°= a3 also. Stage flow coefficient and stage Reaction are o = 0.5 & R = 50%. The at mean radius is aj = flow area at inlet is A1 = 0.372 m?. Determine: (a) The axial velocity through the stages Cz (b) The mass flow rate m; and (c) The power (kW) W required to drive the compressor.
