Mixing and agitation

   Introduction

 The book is an interest textbook for an undergraduate course in chemical process engineering,  which emphasizes the systematic application of fundamental principles (e.g., macroscopic mass, energy, and momentum balances and economics) to the analysis of a variety of  transport phenomena and unit operation problems of a practical nature , can also be used in courses in conjunction with standard textbooks for chemical engineering . Although it is written for students majoring in chemical engineering Analysis methods of many operations have been taken from the recent technical literature. The scope of coverage applications included fluid-particle separation methods (e.g., gravity and centrifugal settling, sedimentation, filtration etc), packed columns, fluidized beds,. The treatment is from the viewpoint of the process engineer, who is concerned with equipment operation, performance, sizing, and selection, as opposed to the details of mechanical design or the details of flow patterns in such situations. This book includes numerous problems that illustrate these applications at the end of each chapter. For the practicing engineer, this book serves as a useful reference for the working equations that govern many applications of practical interest. 

   Chapter 1 covers the basic concepts of mathematical formulations of the rate of input and rate of output terms , the total flux of any quantity is the sum of its molecular and convective fluxes. Chapter 2 deals with the formulation of the inlet and outlet terms when the transfer of matter takes place through the boundaries of the system by making use of the transfer coefficients, i.e., friction factor, heat transfer coefficient, and mass transfer coefficient. The correlations available in the literature to evaluate these transfer coefficients. Flow through circular and non-circular ducts are also discussed in chapter 3. Empirical correlations for various situations are listed. Internal flows of Newtonian and non-Newtonian incompressible fluids and external flow developing region, fully developed flow conditions, constant wall temperature and constant wall heat flux are some of the conditions analysed. fluid-particle separation methods (e.g., centrifugal, sedimentation, filtration), packed columns, fluidized beds, sedimentation. The treatment is from the viewpoint of the process engineer, who is concerned with equipment operation, performance, sizing, and selection, as opposed to the details of mechanical design or the details of flow patterns in such situations are covered through chapter 4 to7

    Chapters 8 and 9 including agitation and mixing of fluid process and heat transfer associated with mixing process. Chapter 10 deals with humidification and cooling tower was discussed  finally.
