Designed for both one- and two-course sequences, this guide helps learners transition to the engineering way of thinking, as they master abstract thermodynamics concepts in the context of real-world applications and practical calculations. Both rigorous and accessible, this concise guide offers focused coverage of everything students need to learn at the sophomore/junior undergraduate level, without unnecessary details or derivations. To support most instructors' approaches to teach chemical engineering thermodynamics, Part I focuses on the First and Second Laws, with applications to pure fluids (e.g., power generation and refrigeration cycles. Part II focuses on phase equilibrium (vapor/liquid, ideal and non-ideal solutions) as well as chemical equilibrium. Updates to this edition include improved organization, more concise coverage of phase equilibrium theory, expanded coverage of flow processes, and many new examples, especially in distillation.
