 “Organization according to control-volume ideas is thus not only simpler but brings clearer understanding
of the physical principles common to otherwise disparate situations.”

“In the end the requirements that have tipped the scales in favor of control-volume analysis lie in the goal or
mission of the engineer—to design and produce useful artifacts.” 

“Practicing engineers are always on the lookout for more effective tools with which to think and do.” 

“By organizing knowledge according to physical laws rather than known problems, it aids in recognizing a
control-volume problem when met in an unfamiliar disguise.” 

“Control-volume analysis, by setting up an explicit method of bookkeeping for the various flow quantities,
provides such a procedure for the many engineers who must deal with fluid-mechanical devices.”

“Control-volume analysis is useful precisely because it provides a framework and method for thinking
clearly about a large class of the often confusing problems that arise in engineering design.”

The words above were originally written about the development of the control volume (2) as a tool for
analysis in thermodynamics and fluid mechanics. However, if you replace the phrases “control-volume
ideas” and “control-volume approach” with the phrase “system, accounting, and modeling approach,”
the words apply equally well to the thrust of this textbook.
The current textbook is based on a different paradigm for organizing an engineering science core—a
system, accounting, and modeling approach—that emphasizes the common, underlying concepts of
engineering science. Although this approach is not necessarily new, as most graduate students have
been struck by this idea sometime during their graduate education, its use as the organizing principle
for an undergraduate curriculum is new. By focusing on the underlying concepts and stressing the
similarities between subjects that are often perceived by students (and faculty) as unconnected topics,
this approach provides students a framework for recognizing and building connections as they learn
new material.

(2) A control volume is a region in space as opposed to a fixed quantity of matter that is used for analysis. In
mechanics, the use of a control volume is called the Eulerian approach while using a control mass, a fixed quantity
of matter, is called the Lagrangian approach
