Although there are many excellent introductory and advanced textbooks on thermodynamics and fluid mechanics, there are very few that deal with both topics. Of those that address both subjects, they tend to be divided into multiple parts that deal with thermodynamics and fluid mechanics separately.
Hence, Thermo-Fluid Engineering I, a course package specifically for use in teaching this introductory course—ENGI 2102: Thermo-Fluid Engineering I. The text is organized so as to clearly demonstrate commonalities between thermodynamics and fluid mechanics. Although the course package was specifically developed for ENGI 2102, it could potentially also be used for other combined introductory courses in thermodynamics and fluid mechanics.
