Each stage of an axial-flow compressor is 0.5 reaction,, has the same blade speed and the same flow outlet angle of 30 deg relative to the blades. the mean flow coeficcient is constant for all stages at 0.5. At entry to the first stage the stagnation temperature is 278 K, the stagnation pressure 101.3 kPa, the static pressure is 87.3 kPa and the flow area 0.372 m2. Using compressoble flow analysis determine the axial velocity and the mass flow rate. Determine also the shaft power needed to drive the compressor when there are 6 stages and the mechanical efficiency is 0.99.
