2 Engineering Thermodynamics AT 2203 ENGINEERING THERMODYNAMICS 3 1 0 4 OBJECTIVE To achieve an understanding of principles of thermodynamics and to be able to use it in accounting for the bulk behaviour of the simple physical systems. To provide in-depth study of thermodynamic principles, thermodynamics of state, basic thermodynamic relations, Principle of Psychrometry & Properties of pure substances To enlighten the basic concepts of vapour power cycles. UNIT- I: BASIC CONCEPT AND FIRST LAW 9(L)+3(T) Basic concepts - concept of continuum, macroscopic approach, thermodynamic systems - closed, open and isolated. Property, state, path and process, quasi-static process, work, modes of work, Zeroth law of thermodynamics – concept of temperature and heat. Concept of ideal and real gases. First law of thermodynamics – application to closed and open systems, internal energy, specific heat capacities, enthalpy, steady flow process with reference to various thermal equipments. UNIT-II: SECOND LAW, ENTROPY AND AVAILABILITY 9(L)+3(T) Second law of thermodynamics – Kelvin’s and Clausius statements of second law. Reversibility and irreversibility. Carnot cycle, reversed carnot cycle, efficiency, COP. Thermodynamic temperature scale, Clausius inequality, concept of entropy, entropy of ideal gas, principle of increase of entropy – Carnot theorem, absolute entropy, availability. UNIT-III. PROPERTIES OF PURE SUBSTANCE AND STEAM POWER CYCLE 9(L)+3(T) Properties of pure substances – Thermodynamic properties of pure substances in solid, liquid and vapour phases, phase rule, P-V, P-T, T-V, T-S, H-S diagrams, PVT surfaces, thermodynamic properties of steam. Calculations of work done and heat transfer in non-flow and flow processes. Standard Rankine cycle, Reheat and regenerative cycle.
3 Engineering Thermodynamics UNIT-IV IDEAL & REAL GASES AND THERMO DYNAMIC RELATIONS 9(L)+3(T) Gas mixtures – Properties of ideal and real gases, equation of state, Avagadro’s law, Vander Waal’s equation of states, compressibility, compressibility chart. Dalton’s law of partial pressure, Exact differentials, T-D, relations, Maxwell relations, Clausius Clapeyron equations, Joule Thomson Coefficient. UNIT-V PSYCHROMETRY 9(L)+3(T) Psychrometry and psychrometric charts, property calculations of air vapour mixtures. Psychrometric process – Sensible heat exchange processes. Latent heat exchange processes. Adiabatic mixing, evaporative cooling, problems. TUTORIALS 15 TOTAL : 60 (Use of standard thermodynamic tables, Mollier diagram, Psychometric chart and Refrigerant are permitted) TEXT BOOKS 1. Nag.P.K., “Engineering Thermodynamics”, Tata McGraw-Hill, New Delhi, 2007.
