Application exercise

Exercises 2.I-2.III and 2.V are classical ones. Exercise 2.IV compares the results of a local approach to those yielded by the global approach, establishing a link with Chapter 1. Exercises 2. VI and 2.VII are more complex. In those cases, the flow does not dissipate energy in certain subdomains, while in others it dissipates some. Based on Borda s model, it will be assumed that energy is conserved in regions where the flow is convergent (the available cross section diminishes) and that dissipation occurs in domains where a sudden expansion occurs.

The applying element of the REACT methodology involves learning by putting concepts to use. In the ABC series, the application exercises often take the form of word problems, not unlike those found in many textbooks. But they are different in two fundamental respects First, they pose realistic (often occupational) situations. Second, they demonstrate the usefulness of academic concepts outside the classroom. Both of these differences add motivation to the learning experience. Consider the following, a typical word problem from a chemistry lesson on pH. 

These are sample activities of one particular subunit of the Water unit. Every subunit in the ABC series provides comparable occupation-specific activities for the topics under discussion. The ABC application exercises and activities have proven effective because they are realistic and are applicable to a broad range of students current and possible future lives outside the classroom (as consumers, family and community members, employees, and citizens). 

There are a number of points in addition to those quoted by Busvine (1971) to be observed in a topical application exercise to minimize variation in results,...

The main intent of this book is to provide a basis for the chemist to interpret mass spectra for the solution of particular structural problems. Wherever applicable, exercises and problems are used to help clarify the discussions while providing a valuable opportunity for practicing what is learned. The examples represent a cross section of organic chemistry. 

Theoretical derivations are in general left out, as they are presented repeatedly in previous works. The necessary theory is instead illustrated by practical examples from the literature. Commonly used computer codes to evaluate experimental ESR data are described with examples. Internet addresses to download the software are given, whenever possible. Formulae employed in those programs are reproduced in appendices, when the original literature references are not easily available. The theory and the application parts are to a large extent independent of each other to allow study of a special subject. For reasons of easy access of data and diagrams several examples from the authors own work were employed to illustrate certain applications. Exercises included in the theoretical part are mainly concerned with spectra interpretations, as this is the key issue in the analysis of experimental data. 

The results of this application exercise are taken up again in section 14.1 of Chapter 14. As can be seen, dimensional analysis is very critical and crucial in the analysis of physical phenomena, at a first level by determining the association of physical parameters that enable results to be expressed, and at a second level, when the exact case arises, by predicting the dimensional form of physical laws for certain asymptotical situations. We have reached this second level in this example.
