This text has been prepared with the primary goal of assembling the broad range of fundamental equations of fluid mechanics and auxiliary relations in fluids.  The text has been written as a reference text to be used by practicing engineers, scientists, students and instructors.  It is presumed that the reader has had reasonable exposure to fluid mechanics. 

Formulations are presented with the necessary explanations, and, when appropriate, they are expressed in different coordinate systems.  Furthermore, different forms of the equations, based on the imposed assumptions, are provided.  The governing equations of fluid mechanics are presented in four chapters, whereas computational fluid mechanics is presented in Chapters Five and Six, and auxiliary relations and fluid properties are presented in Chapter Seven.  An extensive set of conversion factors is presented in Chapter Eight, and some selected mathematical relations are presented in Chapter Nine.
