ME2202 Lecture Notes 

Syllabus :


UNIT I BASIC CONCEPT AND FIRST LAW
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
Second law of thermodynamics – Kelvin’s and Clausius statements of second law.
Reversibility and irreversibility. Carnot theorem, Carnot cycle, reversed carnot cycle,
efficiency, COP. Thermodynamic temperature scale, Clausius inequality, concept of
entropy, entropy of ideal gas, principle of increase of entropy – availability.

UNIT III PROPERTIES OF PURE SUBSTANCE AND STEAM
POWER CYCLE
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 nonflow
and flow processes. Standard Rankine cycle, Reheat and regenerative cycle.

UNIT IV IDEAL AND REAL GASES AND THERMODYNAMIC
RELATIONS
Gas mixtures – properties ideal and real gases, equation state, Avagadro’s Law, Vander
Waal’s equation of state, compressability factor, compressability chart – Dalton’s law of
partial pressure, exact differentials, T-D relations, Maxwell’s relations, Clausius
Clapeyron equations, Joule –Thomson coefficient.

UNIT V PSYCHROMETRY
Psychrometry and psychrometric charts, property calculations of air vapour mixtures.
Psychrometric process – Sensible heat exchange processes. Latent heat exchange
processes. Adiabatic mixing, evaporative cooling
