This is Part – III of the book: “Basic Thermodynamics: Software Solutions”.
Here, Second Law of Thermodynamics and Entropy are dealt with.
After explaining the concepts of Thermal reservoir, Heat Engine, Refrigerator and Heat Pump and their efficiency / coefficient of performance (COP) , two important statements of II Law, viz. Kelvin – Plank statement and Clausius statement are given. Carnot cycle, its efficiency etc are explained next.
Entropy, being an ‘abstract’ concept, is better studied by seeing how it is applied in the analysis of commonly encountered processes.
We study entropy changes for various processes involving pure substances, incompressible substances and ideal gases.
Entropy principle is used to analyze some practically important cases.
‘Entropy balance’ for various systems is studied.
Above topics are illustrated by solving several problems using Mathcad, EES and TEST software.

This book deals with two chapters: Psychrometrics and Reactive systems.
Under Psychrometrics, which is the study of properties of air-water vapor mixtures, we, first give the definitions of various terms and also the thermodynamic equations to determine various psychrometric properties. Then, some psychrometric processes adopted in air-conditioning are explained with the help of Psychrometric chart. Two very good stand-alone calculators to quickly calculate various Psychrometric properties are explained.
Several very useful Functions are written in Mathcad to calculate various psychrometric properties. A summary of the Mathcad Functions written is also provided.
Under Reactive systems, basically, we deal with combustion. Combustion equations and their balancing by atoms of constituents is presented.
Stoichiometric Air-Fuel (AF) ratio, actual AF ratio, percent excess air, equivalence ratio etc are explained. Enthalpy of formation of compounds, enthalpy of combustion or enthalpy of reaction are explained.
Tables of enthalpies of formation and other tables for enthalpies of different species required for combustion calculations are presented.
Heat transfer during combustion and Adiabatic flame temperature are explained.
Also, many useful functions are written in Mathcad and EES and several problems are solved using Mathcad, EES and TEST to illustrate the problem solving techniques in both the chapters.

EES Functions are also written for entropy changes for various processes. Use of these Functions in problem solving is demonstrated.
Exergy balance and II Law analysis of systems is explained.

This is Part-II of the four-part e-book “Software Solutions to Problems in Basic Thermodynamics”
Part-II contains solved problems on following topics: Zeroth Law, Heat and Work, First Law of Thermodynamics for a closed system and for flow processes.
In this book, problems are solved using three popular software, viz. “Mathcad”, “Engineering Equation Solver (EES)” and “The Expert System on Thermodynamics (TEST)”. Some ‘free software’ are also explained.
An introductory chapter in Part-I gives a brief overview of the software used.
At the beginning of each chapter, a concise compilation of statements, definitions and formulas used in that chapter is given.
Comments are included generously in the codes so that the logic behind the solutions is clear.

This book deals with two important chapters in Applied Thermodynamics, viz. “Cycles for Gas Turbines and Jet propulsion” and “Vapor power cycles”.
Brayton cycle is the air standard cycle for Gas Turbines. Modifications to the Ideal Brayton cycle to increase the thermal efficiency are also studied; these include adding a regenerator and resorting to multistage compression in the compressor and multistage expansion in the turbine.
Jet propulsion cycle used for aircraft propulsion is also analysed.
Several Functions/ Procedures are written in Mathcad and EES to determine network, thermal efficiency etc of the Ideal and actual Brayton cycles.
“Vapour Power cycles” are analyzed with particular reference to Ideal Rankine cycle and its variations, used in Steam Power Plants.
Several useful Mathcad Functions are written for properties of steam in superheated and two-phase regions, since Mathcad does not have built-in Functions for steam, and these will be extremely useful in solving problems on Rankine cycle.
Also, many useful Functions/Procedures are written in EES for different variations of Rankine cycle.
In both these chapters, problems from University question papers and standard textbooks are solved with Mathcad, EES and TEST.

This book contains three chapters, viz. Refrigeration cycles, Air compressors and Thermodynamic relations:
1. Under ‘Refrigeration cycles’, following cycles are analyzed: Ideal and actual vapour compression cycle, Ideal and actual reversed Brayton cycle (or, Bell Coleman cycle). Several useful Mathcad Functions are written for properties of Refrigerant- R134a in superheated and two-phase regions, which are used in solving problems. Also, useful Mathcad Functions are written to facilitate easy calculations for all these cycles. And, many useful Functions/Procedures are written in EES for different variations of ideal vapor compression refrigeration cycle.
2. Under ‘Air compressors’, reciprocating air compressors (both single stage and multi-stage) are analyzed. Formulas to calculate various parameters such as: volumetric efficiency, work required for actual compression, isothermal efficiency, minimum work required for two- stage (or multistage) compression with perfect inter-cooling etc. are presented.
3. Under ‘Thermodynamic relations’, relations are presented to calculate ‘Thermodynamic properties’ which are impossible or difficult to measure (such as: entropy, internal energy, enthalpy, Helmholtz function and Gibbs function), in terms of measurable quantities such as pressure, volume and temperature. Topics dealt with are: Maxwell’s equations, TdS equations, heat capacity relations, energy equations, Joule – Kelvin effect, Clausius - Clapeyron equation etc. which are practically important.
4. In these chapters, problems from University question papers and standard Text books are solved with Mathcad, EES and TEST.
