The gaseous materials most frequently encountered in fan engineering are air and water vapor accordingly, most of the data are for these substances. This chapter deals with the thermodynamic properties, especially pressure, temperature, humidity, density, and enthalpy Transport properties, such as viscosity, thermal conductivity, and diffusivity, are dealt with in subsequent chapters. The thermodynamic and transport properties of gases and vapors are important in fan engineering.

Part IV is a collection of miscellaneous topics which readers have found useful.įeel you need to start at a higher level? Read our article An Insiders Guide To Fans In The Industrial Sectors.Ĭhapter 1 Properties of Air and Other Gases.

Other handbooks deal with some of these subjects in much greater detail. Here too, the convenience of the reader is the main reason for including several of these topics.

Part III is concerned with specific fan applications.

Even those portions which are concerned with design may be valuable to the user, since an understanding of what makes a fan work may lead to better applications. Although there is some discussion of fan design, both aerodynamical and mechanical, the emphasis is on those topics which should concern the user.

Each subject has a bearing on fans or fan applications. Although these topics are generally treated in other handbooks, they are presented here for the convenience of the reader. We are pleased to be able to present the Ninth Edition of Fan Engineering, which is recognised worldwide as THE definitive handbook on fan design and fan applications, and reflects our lengthy experience with fan design.įan Engineering has been written as a handbook for engineers who use fans.
