Microscopic and Macroscopicapproachof thermodynamics system, Surroundingsandproperty, intensive and extensive properties,measurementof temperature,Zerothlaw ofthermodynamics,temperature scale, ideal andidealgas thermometer, reversibility and irreversibility, quasi static process, specific heats for ideal gases, thermodynamic equilibrium.
First law of thermodynamics:Statement of First law, heat and work interactions, thermodynamic work and internal energy, energy as property of system, first law applicable to closed system, thermodynamic processes and calculation of work, heat transfer, internal energy, heat as path function, first law analysis of flow processes and limitation, calculation of work done during flow process
Second law of thermodynamics:Physical description of second law, Kelvin-Planck andClausisstatement of second law of thermodynamics, Equivalence of Kelvin-Planck-Clausisstatement, Reversible and irreversible processes, Carnot theorem.Classiusinequality, calculation of entropy changes during various thermodynamic processes principle of Entropyincrease ,T-S diagram, Available and Unavailable energies in steady flow, second law of control volume, Helmholtz and Gibb’s function ,Available function for flow and non-flow process
Thermodynamicproperties of Fluids:Properties of pure substances,concept ofphase change, graphical representation of pressure, volume and temperature, (PVT)-T and H diagram, properties of steam, use of steam tables andMollierdiagram,, thermodynamic relations involving entropy, enthalpy, internal energy, Maxwell relations andClapeyronequation.
Air standard cycles & Combustion of fuels:Air standard cycles-Otto, Diesel, dual combustion cycle,
andRankinecycle. Classification of fuels, high calorific value, low calorific value, advantages and disadvantages of liquid fuels over solid fuels and gaseous fuels over other fuels, calorific value of fuels—higher calorific value (HCV) and lower calorific value (LCV)—determination of HCV and LCV of fuels by Bomb calorimeter and Junker’s gas calorimeter, Theoretical (stoichiometric) mass and volume of air required for complete combustion of fuels, excess air supplied, actual amount of air, gravimetric and volumetric analysis of fuels, conversion of gravimetric to volumetric analysis and vice-versa, mass of carbon in flue gases and analysis of flue gases byOrsatapparatus.
