3) Consider a 3-stage air axial compressor. It has stage pressure ratios and total-to-total efficiencies as follows: 1st stage: PR=1.6, nt=0.87, 2nd stage: PR=1.4, Ntt=0.89, 3rd stage: PR=1.3, Ntt=0.90. Compute a) compressor pressure ratio, b) compressor overall total-to-total efficiency, c) compressor polytropic efficiency. 3) Consider a 3-stage air axial compressor. It has stage pressure ratios and total-to-total efficiencies as follows: 1st stage: PR=1.6, nt=0.87, 2nd stage: PR=1.4, Ntt=0.89, 3rd stage: PR=1.3, Ntt=0.90.
