N2  - "This text provides students and professionals at all levels with a highly accessible reference. The coverage allows for a smooth transition from the study of thermodynamics, fluid dynamics, and heat transfer to the subject of turbomachinery, with chapters organized so that more difficult material is left to the later sections. Chapters relate turbomachinery to new areas such as wind power and three-dimensional effects in axial turbomachines, providing information on several types of turbomachinery rather than concentrating specifically on one type"--
