Engineering Thermodynamics by Dr.G.K.Vijayaraghavan from Lakshmi Publications
Author: Dr. G.K.Vijayaraghavan Publisher: Lakshmi Publications Regulation: 2017 Binding: PaperBack (PDF) Engineering Thermodynamics - ResearchGate 20 Nov 2018 — The textbook Engineering Thermodynamics by Dr
Dr. G.K. Vijayaraghavan’s Engineering Thermodynamics is a widely used textbook, particularly tailored for students under Anna University and related technical institutions. The book is noted for its systematic presentation and adherence to specific semester syllabi for mechanical and automobile engineering. Core Content & Unit Structure
The textbook is typically organized into five primary units that cover the essential pillars of classical thermodynamics:
Unit I: Basic Concepts and First LawFocuses on thermodynamic systems, properties (intensive/extensive), and the concept of continuum. It covers the Zeroth Law, temperature scales, and the First Law of Thermodynamics as applied to both closed and open systems (steady flow processes).
Unit II: Second Law and Availability AnalysisExplores the limitations of energy conversion, including the Carnot cycle, Clausius inequality, and the concept of entropy. It also introduces availability (exergy) and irreversibility.
Unit III: Properties of Pure Substances and Steam Power CyclesExamines the formation of steam, thermodynamic property diagrams (P-V, T-s, h-s), and the use of Steam Tables and Mollier charts.
Unit IV: Ideal and Real Gases & Thermodynamic RelationsCovers the behavior of perfect gases, equations of state (like Van der Waals), and critical thermodynamic relations used in engineering calculations.
Unit V: Gas Mixtures and PsychrometryDiscusses the properties of gas mixtures, Dalton’s and Amagat’s laws, and psychrometric processes such as humidification, dehumidification, and cooling, which are vital for HVAC applications. Verified Sources for the Textbook

Engineering Thermodynamics textbook by Dr. G.K. Vijayaraghavan Dr. S. Sundaravalli
is a widely recognized academic resource, specifically tailored for the Anna University syllabus for Mechanical and Automobile Engineering. The Story of the Textbook The journey of this book began with its First Edition in May 2005 . Published by Lakshmi Publications
, it was designed to solve a common student dilemma: existing thermodynamics books were often too bulky or lacked the specific clarity needed for university examinations. Over nearly two decades, the book evolved through fourteen revisions to keep pace with changing academic regulations, reaching its Fully Revised Fourteenth Edition in June 2018. Book Overview The text is structured into five core units
, guiding students from basic principles to complex thermal systems: Unit 1: Basic Concepts & First Law But I Need a Digital Copy
– Introduces the zeroth law and energy balance for open and closed systems. Unit 2: Second Law & Entropy
– Covers heat engines, refrigerators, and the concept of availability. Unit 3: Pure Substances & Steam Cycles – Explores p-V and T-s diagrams and steam power cycles. Unit 4: Ideal & Real Gases – Discusses thermodynamic relations and gas behavior. Unit 5: Gas Mixtures & Psychrometry – Elaborates on air-vapor mixtures and cooling processes.

Part 1: Why Vijayaraghavan’s Engineering Thermodynamics Stands Out
Before hunting for a PDF, it is critical to understand why this specific textbook is so highly recommended. Written in the Indian pedagogical context but applicable globally, the book bridges the gap between theoretical rigor and practical application.
Part 3: How to Spot a Fake or Unverified PDF
If you ignore the warning and still look for user-uploaded PDFs (e.g., on Telegram, Reddit, or DocPlayer), use this checklist to verify the file before opening it.
| Check | What to Look For | Red Flag | |-------|------------------|-----------| | File Extension | Ends in .pdf | Ends in .exe, .scr, .zip (password-protected) | | File Size | ~35-50 MB for a clean scanned 600-page book | Less than 5 MB (likely just a chapter or malware) | | Metadata (Right-click → Properties) | Author = Vijayaraghavan; Publisher = McGraw-Hill | Author = “Admin” or blank | | Page Count | 650-700 pages (depending on edition) | 200 pages (truncated) | | Watermarks | None in official e-book, but scans may have library stamps | “CONFIDENTIAL” or “PROOF COPY” – likely unauthorized preview | | Chapter 1 Present? | Should cover “Basic Concepts” starting with thermodynamic definitions | Starts abruptly with “Steam tables” – missing half the book |
Quick test: Search for the phrase “Zeroth law of thermodynamics – thermal equilibrium” in the PDF. In the genuine book, it appears in Chapter 1, page 8-9. If the PDF has garbled characters (e.g., “Zer0th l@w” or missing equations), it is an unverified OCR scan.
But I Need a Digital Copy! – Legitimate Options
Instead of searching for “free verified PDF,” use these legal, safe, and often affordable methods:
-
McGraw-Hill’s official e-book (Accessible via VitalSource or RedShelf):
- You can rent or buy the official e-book for a fraction of the print price (typically $10–$20 for 180-day rental).
- Features: Highlighting, searchable text, verified content, no malware.
-
Indian University Access (through INFLIBNET – Shodhganga or NDL):
- Indian students with a valid college email can often access the National Digital Library (NDL India). Search for “Vijayaraghavan Thermodynamics” – some partner colleges have institutional licenses for e-textbooks.
-
Google Books Preview (Partial Verification):
- Search for the book on Google Books. You can preview selected chapters (usually chapter 1 and part of chapter 2) for free. This allows you to verify the writing style and format before buying.
-
Second-hand + Scanner Method:
- Buy a used physical copy for ₹200-300 (approx. $3-4) and legally scan it for personal use. While tedious, this gives you a perfectly verified personal PDF without piracy.
✅ Verified Suggestion: If you search for “engineering thermodynamics vijayaraghavan official ebook” on Google Shopping or McGraw-Hill India’s website, you will find the legal rental option. That is the only verified digital copy you can trust.
Step 2: Scan with VirusTotal
Go to virustotal.com. Upload the file (max size 650 MB for free accounts). If any of the 60+ antivirus engines flag it as malicious, delete it.
