(12 Points): Refer to Problem 8.5: A compressor stage develops a pressure ratio of - 1.6. Its polytropic efficiency is -0.90. Calculate the stage total temperature ratio and compressor stage adiabatic efficiency n. Assume y 1.4. Use Equation 8.36 to assess your calculation of n 1.4-1 1.4 0.9= n-1 n n=1.465 1.465-1 TS 1.6 1.465 = 1.4-1 =1.16 (1.6) 141.143 ns= 1.143-1 1.16-1 =0.893 89.3% compressor stageadiabatic efficiency
