Unit Operations of Chemical Engineering 7th Edition by Warren McCabe, Julian Smith and Peter Harriott incorporates new material and extra problems, however the basic construction, basic degree of remedy, and total length are largely unchanged. This is an introductory text, written for undergraduates in their junior or senior yr who have completed the standard programs in arithmetic, chemistry, physics, and an introduction to chemical engineering.
The elementary information of material and energy balances is assumed. As a result of it incorporates up-to-date correlations for heat transfer, mass transfer, and equipment design, this text should also be useful to chemists and engineers in industry. Separate chapters are devoted to every of the principal unit operations, grouped into four sections: fluid mechanics, heat transfer, mass transfer and related separations, and operations involving particulate solids.
One-semester programs may be primarily based on any of those sections or mixtures of them. Bioengineering is just not treated as a separate matter, but examples of food processing, bioseparations, and diffusion in biological programs are included in varied chapters. The part on fluid viscosity in Chap. 3 is expanded to incorporate easy theories for gases and liquids. In later chapters, comparable theories for thermal conductivity and diffusivity are discussed and comparisons made.
The analogies among momentum transfer, diffusion, and heat conduction are given extra emphasis, and the section on transient diffusion is expanded to include an instance of controlled-release drug delivery. New material in Chap. 25 offers with using powdered carbon to treat aqueous waste in tanks, and expanded-bed adsorption that can be used for purification of fermentation broths.
Chapter 29 has a new part on diafiltration, a course of often utilized in protein purification. There's additionally an expanded treatment of ultrafiltration and microfiltration of protein and polymer solutions. The discussion of filter cake washing is totally revised and a plot of some knowledge is included. Warmth pipes and plate-sort exchangers are included within the chapter on heatexchange equipment.
The distillation chapters contain revised sections on flash distillation, flooding limits, and plate efficiency. Correlations for drying charges and a therapy of dryer thermal effectivity have been added. The top-of-chapter issues are new or revised for this edition. Practically all the problems can be solved with the help of a pocket calculator, however for a couple of, a computer solution is preferable.
