Determine the mass of compressed air in a scniba diving tank, given the following informadon. The internal volume of the tank is 10 L and the absolute air pressure inside the tank is 20.8 MPa. The temperature of die air inside the tank is 20°C. Use the ideal gas law to analyze this problem. The ideal gas law is given by

Presentation of each optimization technique is followed by examples to illustrate an application. We also have included many practically oriented homework problems. In university courses, this book could be used at the upper-division or the first-year graduate levels, either in a course focused on optimization or on process design. The book contains more than enough material for a 15-week course on optimization. Because of its emphasis on applications and short case studies in Chapters 11-16, it may also serve as one of the supplementary texts in a senior unit operations or design course. 

In this book, boxes are used for specific derivations and may be viewed as "appendixes" placed in the text. Examples are given to illustrate how to apply the concepts and equations. Homework problems are provided at the end of every chapter. Appendixes offer additional information related to the presentation of the text. A lengthy reference list is at the end of the book. 

My childhood was happy, conventional, and middle class. We lived in a small house in Shorecrest, New Jersey, just a few blocks away from Highway 35.1 remember our split-level home at 39 Richard Terrace and the nearby Bodman Park where I used to play. Both parents helped me with my homework as I grew up—my dad worked with me on mathematics, and my mom helped me with presentations and posters. My father also continually drew mazes for me to solve with pencil and paper. 

A physical chemistry instructor is faced with a number of decisions the goals and objectives of the course, the level of presentation, the choice of textbook, what topics to include, the sequence of topics, the balance between fundamentals and applications, the amount of homework to assign, the use of classroom time, and so forth. Of the students in the class, only a small fraction might intend to become physical chemists. The physical chemistry instructor must make his or her decisions in this context. 

We have attempted to present nuclear chemistry and the associated applications at a level suitable for an advanced undergraduate or beginning graduate student. We have assumed the student has prior or, concurrent instruction in physical chemistry or modem physics and has some skills in handling differential equations. We have attempted to sprinkle solved problems throughout the text, as we believe that one learns by working problems. The end-of-the-chapter homework problems... 

This equation can be obtained in a straightforward manner by assuming that the specific viscosity of the (dilute) solution is simply the sum of the contributions from all the chains present, then you just work through the algebra shown in Equations 12-49. (We know that you won t do this unless we make you, so get ready for a nasty homework.)... 

Each chapter is broken into sections wdth the first section always stating the objectives of the chapter, and the last section always providing a summary of the chapter. In the text, problems are worked to elucidate the points discussed. Finally at the end of each chapter there are tmworked problems that the students can do for homework. The book attempts to provide a large list of references for specific concepts and ideas presented elsewhere, and we hope that the reader will refer to these references for the derivation of specific equations not presented. This book is hi ily mathematical in comparison with other texts in the field, because this field should be mudi more quantitative than heretofore presented. With these mathematics, the field of ceramic powder processing can become more quantitative in the future. 

This book teaches both principles and design. Principles are enunciated in the simplest way possible. Equations presented are first derived, except those that are obtained empirically. Statements such as It can be shown... are not used in this book. These authors believe in imparting the principles and concepts of the subject matter, which may not be done by using it-can-be-shown statements. At the end of each chapter, where appropriate, are numerous problems that can be worked out by the students and assigned as homework by the instructor. 

The material is presented in a manner that facilitates sequential development of understanding and expertise either in a course or in self-study. Illustrative examples are interspersed throughout the text to show how the principles described are applied to common impedance problems. These examples are in the form of questions, followed by the solution to the question posed. The student can attempt to solve the problem before reading how the problem is solved. Homework problems, suitable either for self-study or for study under direction of an instructor, are developed for each chapter. Important equations and relations are collected in tables, which can be easily accessed. Important concepts are identified and set aside at the bottom of pages as they appear in the text. Readily identifiable icons are used to distinguish examples and important concepts. 

Part of my objective was achieved, as evidenced by the following excerpt from a very thorough review of the first edition of my book, written by Professor Mark J. McCready, a well-known expert in chemical engineering education If the topics that are needed for a given course are included in this text, I would expect the educational experience to go smoothly for both student and instructor. I think that students will like this book, because the explanations are clear, the level of difficulty is appropriate, and the examples and included data give the book very much of a handbook flavor. Instructors will find that, overall, the topics are presented in a logical order and the discussion makes sense there are many examples and lots of homework problems (McCready, M. J., AlChE J., Vol. 49, No. 1, January 2003). 

We offer end-of-chapter exercises for every type of student and for every kind of homework assignment questions that promote group learning exercises that reinforce student understanding and problems that present the ultimate challenge with increased rigor and by integrating multiple concepts. We have added biochemistry problems to make the connection for students in the course who are not chemistry majors. 

Another audience of the therapist s colleagues was arranged for her to practise the presentation that she was due to make to her fellow medical students in a fortnight, but this time it was also videotaped. As part of the previous week s homework, she had made predictions about how she thought she would cope and how people in the audience would react. These included that she would blush, shake, and look awkward, and that others would look embarrassed, avoid eye contact with her, and not ask any questions at the end. In addition, she agreed to start off using several safety behaviours, but then drop them one by one and note what effects this had on her anxiety. 

Her loss of confidence, due to an unforeseen consequence of some homework, was alarming, given that it occurred only a few days before she was due to present to her fellow medical students. Fortunately, her confidence was restored by a productive session in which she was able to draw on skills gained earlier in therapy in completing thought records, which were then consolidated by a written plan to help boost further her confidence and belief that she could cope. The problem with the homework may have been avoided if she had been given specific instructions to view the video as if she were watching someone towards whom she felt well disposed (Butler and Hackmann 2004). 

This is where I have come to rescue you You do not necessarily have to go back to your prerequisite math courses. You already have, on some subconscious level, all the mathematical skills you need. So here is your handy little Rescue Manual. You can read just the parts of this book you think you need. There are no homework assignments. Instead, we want to help you do the problems you already have in your science courses. You should, of course, work through and understand steps we have omitted in presenting important results. In many instances, it is easier to carry out a multistep derivation in your own way rather than to try and follow someone else s sequence of manipulations.
