Competitive examinations have become inevitable nowadays foradmission to graduatecourses and placement in chemical and alliedindustries, for undergraduate students in chem-ical engineering.For such examinations, apart from a wide knowledge of all aspectsof unitoperations of chemical engineering a quick wit to solve thequestions/problems is absoluteleyessential. Exhaustic revision ofall these operations studied in earlier semesters is atediousprocedure. A quick insight into the same along withsolutions to short answer objectivequestions or problems isnecessiated. With this objective in view, the author has madeanattempt to prepare this monograph after going through manyquestion papers of this typefrom several universities along with anintensive study of the operations covered.
I had the oppurtunity of revising the text and providingacademic advice wherever nec-essary. I am confident this effort ofthe author will be well received by the budding chemicalengineerstaking their first degree from engineering colleges.

A set of instant notes are given for various important topics inthe core subjects ofChemical Engineering. I hope this set of topicsdetailed in this book will be of extreme useto the undergraduatestudents and practicing engineers for enhancing and checkingtheirknowledge in the core concepts of the subject. In anycompetitive examination due weightageis being given to objectivetype questions. In this book I have also given objectivetypequestions which will be useful for the chemical engineers andstudents for their preparation.

6 FOREWORD I have known the authors, m subbu, d k sandilya, and k nagarajan, almost for the past 15 years and am well familiar with their interests and abilities since they used to interact with me both professionally and personally during their doctoral study times at IIT Madras. Dr. M. Subramanian (m subbu) used to discuss with me his research topic on photocatalysis, attend my classes on Chemical Reactor Theory at the masters level, and take necessary inputs from me as and when required. Dr. D. Krishna Sandilya (d k sandilya) was helping me as a teaching assistant (TA) for the course of Chemical Reactor Theory. He used to solve every problem of Levenspiel and was closely following the developments in the field of Chemical Engineering. Dr. K. Nagarajan was doing Ph.D under my supervision in the area of Fluidization. He was doing his experiments enthusiastically and systematically. Each of these authors used to share their understanding of the Chemical Engineering subjects with me and was found to be having good knowledge with a keen interest towards teaching career. Based on my observation during the constant interaction sessions with the above authors, I believe that they are teaching at their respective institutes with good enthusiasm by citing contemporary examples which can give clear understanding of the concepts. I came to know about the other two authors, Mr. S. Siddarth & Mr. R. Pavan Kumar, through Dr. M. Subramanian. They, along with Dr. M. Subramanian, have done an excellent job of solving, compiling and presenting with nice illustrations, the general aptitude aspects of GATE in their book titled GATEway GA to General Aptitude. I could learn that these two authors during their time as students at SSN, Chennai had undergone meticulous preparation for GATE, thereby getting a position in IOCL and BPCL respectively, the dream jobs of every aspiring chemical engineer. I could go through the salient aspects of the book GATEway GA to Chemical Engineering which is logically spread over five volumes. I also observed that the book is presented in a systematic manner, in the form of methodical approach to solutions of GATE-Chemical Engineering questions and questions from other relevant streams of GATE. The solutions to problems are explained with suitable illustrations and well-drawn diagrams, wherever necessary. The title GATEway GA to (understand) Chemical Engineering is really suitable for this book because of rationally explained solutions to the wise and tricky questions of GATE, covering the important features of each subject of Chemical Engineering by the authors. The added beauty of this assiduous project is brought out in terms of legible text and figures because of the typesetting tool L A TEX. I am sure this book will be of immense use for every chemical engineer, for sharpening his/her knowledge. I wish the authors and readers of the book, to have a wonderful future! Happy reading!

7 PREFACE Having a good grasp of the core subjects of engineering and the ability to use this knowledge wisely in order to understand, and solve new engineering and societal problems are desirable characteristics of a smart engineer. Recognizing the connection between the core subjects by means of learning several concepts in a holistic manner paves the way for a professional to be evolved out of an engineer. Chemical Engineering is a fascinating branch of engineering that deals with the profession of utilizing different forms of materials and energy to economically produce a variety of useful products on a commercial scale by means of conducting several physical and chemical operations in a safe and reliable manner. The primary goal of Chemical Engineering discipline, which is in almost 131 years of existence by now, is to benefit the mankind. Graduate Aptitude Test in Engineering (GATE) is an annual examination conducted jointly by the premier institutes of India, viz. the Indian Institute of Science (IISc), Bangalore and the Indian Institutes of Technology (IITs) at Bombay, Delhi, Guwahati, Kanpur, Kharagpur, Madras, and Roorkee, on behalf of the National Coordination Board (NCB) GATE, MHRD, Government of India. GATE tests a candidate s complete understanding of a variety of undergraduate subjects in Engineering. The sharpness of an engineering graduate in the application of his/her knowledge to new situations is also aptly tested in GATE. The syllabus of the examination covers the relevant core subjects of that particular stream. Preparing for this examination is a good experience for any engineering graduate, in recollecting the fundamentals and understanding the connections between subjects. The questions asked in GATE are uniquely designed to test the conceptual understanding of the candidate rather than testing his/her memory. Qualifying GATE examination is a prerequisite for getting admission into higher studies at reputed institutes of India. Marks/Score of GATE examination is also considered as the screening criterion for getting placements in top-notch public sector undertakings (PSU) of India. In other words, GATE is considered as a gateway for entering into elite institutes offering higher studies and/or getting placed in dream companies. The book titled An Insight into Chemical Engineering, written by the first author of this book (m subbu) which was published in the year 2003, covered the solutions for GATE questions of along with brief notes. It was well acknowledged by the chemical engineering community of India for the clarity and concise presentation of the subject. Motivated by this appreciation received, the impetus for writing the present book titled GATEway GA to Chemical Engineering was conceived. This book covers all the core subjects of chemical engineering. Theory in a concise manner for the essential topics with suitable illustrations is provided for 11 subjects of Chemical Engineering and Mathematics in the form of Instant Notes for ready reference. It is assumed that the reader has already gone through the core subjects in detail. With that in mind, only the key points are touched up on in the notes. Otherwise also, an intelligent reader can understand the concepts presented even on the first reading of this book. However, wherever required, elaborate notes on certain concepts is provided. The theory of each subject is followed by Objective Types Questions and Problems with Solutions sections. The present book covers solutions to questions of GATE of chemical engineering (CH) stream, augmented by selected questions of other related 2ff7e9595c
