Stage pressure ratio ( \pi_s = 1.3 ), number of stages ( n = \frac\ln 15\ln 1.3 = \frac2.7080.262 \approx 10.3 ), so 10 stages (final ratio slightly adjusted).
Appendix B: Turbomachinery Design Software Guide Appendix C: Answers to Selected Problems Index Preface to the Fourth Edition The three previous editions of Turbines, Compressors, and Fans have been used worldwide by undergraduate and graduate students, practicing engineers, and researchers in aerospace, power generation, and industrial process industries. The continued evolution of turbomachinery — driven by net-zero carbon targets, additive manufacturing, and digital twins — necessitated a thorough update.
