is a premier core textbook for undergraduate students of chemical engineering and chemical technology. Published by Universities Press , this authoritative work bridges the gap between pure macroscopic physics and complex industrial applications.
| Feature | Description | |---------|-------------| | | The author starts with the why of each law before diving into the how , which helps students internalize the physical meaning rather than just memorizing equations. | | Numerical Emphasis | Over 150 fully solved examples, plus an additional 250+ end‑of‑chapter problems. This volume of practice is invaluable for mastering calculation techniques. | | Data‑Rich Appendices | Thermodynamic property data for a wide range of chemicals (including petroleum fractions) are compiled, reducing the need to consult multiple handbooks. | | Exam‑Oriented | Many problems are directly aligned with the pattern of Indian engineering entrance and graduate exams, making the book a go‑to revision tool. | | Compact Yet Complete | Although the book is relatively thin compared with some Western texts (e.g., “Thermodynamics” by Smith, Van Ness & Abbott), it covers everything a typical B.Tech curriculum demands. |
The textbook spans 14 detailed chapters structured for a comprehensive two-semester undergraduate sequence. Chemical Engineering Thermodynamics Yvc Rao is a premier core textbook for undergraduate students
Chemical Engineering Thermodynamics by K.V. Narayana and Y.V.C. Rao is a comprehensive textbook designed for undergraduate students of chemical engineering. The book provides a clear understanding of the principles of thermodynamics and their applications to chemical processes. It bridges the gap between classical thermodynamics and the specific needs of chemical engineers, focusing on the solution of process problems.
Chemical engineering thermodynamics is the backbone of virtually every process unit in the industry—distillation, reactors, heat exchangers, separation equipment, and even emerging technologies such as carbon capture and utilization. Y. V. C. Rao’s text has earned a reputation among Indian engineering students and faculty for: | | Numerical Emphasis | Over 150 fully
| Category | Equation | Description | |----------|----------|-------------| | | ΔU = Q – W | Internal energy change equals heat added minus work done by the system. | | Enthalpy | H = U + pV | Useful for constant‑pressure processes. | | Second Law (Clausius Inequality) | ∮δQ/T ≤ 0 | Equality for reversible cycles. | | Gibbs Free Energy | G = H – TS | Minimum at constant T, p; ΔG = 0 at equilibrium. | | Ideal Gas EOS | pV = nRT | Basis for many derivations. | | Van der Waals EOS | (p + a/(V_m²))(V_m – b) = RT | a, b = attraction & co‑volume parameters. | | Fugacity (Real Gas) | f = φ p, ln φ = ∫(Z – 1)/p dp | φ = fugacity coefficient, Z = compressibility factor. | | Activity Coefficient (Margules 2‑suffix) | ln γ₁ = A·x₂², ln γ₂ = A·x₁² | A = binary interaction parameter. | | Bubble‑Point (binary) | y_i = K_i x_i, ∑ y_i = 1 | K_i = K‑value = φ_i^L/φ_i^V·(p_i^sat/p). | | Flash Calculation (overall) | F = L + V, z_i F = x_i L + y_i V | Material balances for overall, component, and energy. | | Equilibrium Constant (reaction) | K = ∏ (a_i)^ν_i | a_i = activity of species i. | | Exergy (Closed System) | B = (U – U₀) + p₀(V – V₀) – T₀(S – S₀) | Maximum useful work relative to environment (p₀, T₀). |
