QUESTION 9In a jet engine rotor the high pressure axial compressor rotates at a speed of 15000 rpm. Theoverall stagnation pressure ratio due to compression is 10:1. It was recorded that the air flowsat a rate of 16 kg/s. The stagnation properties at the inlet are 215 kPa and 460K. The poly-tropicefficiency of the compressor is 90%Assume the mean radius of the compressor is constant and equal to 0.25m. Calculate the total-to-total isentropic efficiency of the compressor. Estimate the number of stages required, if thestage loading to be less than 0.45
