White's Fluid Mechanics is praised for its thorough and accurate approach, student friendly writing style, and its concise yet accessible coverage. The electronic version of the text presents these features and more in a CD-ROM with expanded descriptions of certain tables and diagrams through links. The E-Text enhances the text's elegant and solid description of the fundamentals. This fourth edition includes the addition of over 500 new problems, divided categories of "applied problems," "comprehensive applied problems," "design projects," "word problems" and "FE (fundamentals of engineering exam) problems." The book also has an updated, modern design and includes many useful pedagogical and motivational aids such as a perforated "Key Equations Card," boxed equations, and opening chapter photos.
