Question
A high pressure axial flow compressor is driven by
the jet engine at a speed of 1200rpm.An overall
stagnation pressure ratio of 10 is recorded due to
the compression of air. The stagnation
temperature of air at inlet of the compressor is
325K.Polytropic efficiency of compressor is given
as 90% mean radius of the compressor is assumed
to be constant and equal to 0.3 m. Determine the
total isentropic effeciency and estimate the
minimum number of stages required if the stage
loading to be less than 0.3
