: Thermodynamics relies heavily on work and heat sign conventions. Always clarify whether work is done by the system or on the system before starting a problem.

| Unit | Core Topics Covered | | :--- | :--- | | | Covers fundamentals like the concept of continuum, macroscopic vs. microscopic approach, thermodynamic systems (closed/open/isolated), properties, equilibrium states, quasi-static and reversible processes. It also details the Zeroth Law (temperature measurement) and the First Law of Thermodynamics applied to both closed and open systems, including concepts of internal energy, enthalpy, and the steady-flow process. | | Unit 2: Second Law of Thermodynamics & Entropy | Explores the directionality of processes, covering heat reservoirs, heat engines, and refrigerators. It includes a detailed explanation of the Kelvin-Planck and Clausius statements, the Carnot cycle, the Clausius inequality, the concept of entropy, T-s diagrams, and the principle of entropy increase. | | Unit 3: Properties of Pure Substances & Steam Cycles | Focuses on pure substances, their phase change processes, and how to interpret P-V, P-T, T-s, and h-s (Mollier) diagrams. This unit is crucial for understanding steam properties and covers the analysis of standard power cycles like the Rankine cycle, including modifications like reheat and regeneration. | | Unit 4: Ideal & Real Gases, Thermodynamic Relations | Introduces gas mixtures, equations of state for ideal and real gases, and the all-important Maxwell relations and Clausius-Clapeyron equation, which are fundamental for deriving property relationships. | | Unit 5: Psychrometry | A practical unit on air-vapor mixtures. It explains the psychrometric chart and various psychrometric processes such as sensible heating/cooling, humidification, dehumidification, and adiabatic mixing. | Claims otherwise on file-sharing sites almost always result
Beyond its structural alignment, the book is praised for its pedagogical strength. A detailed Amazon review highlights its "exceptional writing" and the "utmost clarity" with which concepts are explained. The book is designed not just for rote learning but for concept building. Its solved examples are described as "thought-provoking" and instrumental in gaining a "good command on this subject".

The core issue is that there is no such thing as a "verified" PDF from an official source. Any PDF found on unofficial websites has bypassed the publisher's legal and quality control processes.
