  4. Content To Be Covered Thermodynamic systems and processes; properties of pure substance; Zeroth, First and Second Laws of Thermodynamics; Entropy, Irreversibility and availability Analysis of thermodynamic cycles related to energy conversion: Rankine, Otto, Diesel and Dual Cycles; Ideal and real gases; compressibility factor; Gas mixtures. Modes of heat transfer, Steady and unsteady heat conduction, Thermal resistance, Fins, Free and forced convection, Correlations for convective heat transfer, Radiative heat transfer-Radiation heat transfer co- efficient; boiling and condensation, Heat exchanger performance analysis.

  5. State 1The Condition of the system is known as the state of the system. State of the system can be identified by thermodynamic property. Path The locus of series of state through which a system passes going from initial state to final state constitute a path.

  6. Rigid Body Body whose dimensions are not meant to change. Eg. Solid container. Flexible Body When the system's body or shape keeps on changing. Eg. A system having a piston

  7. Equilibrium Absence of tendency for spontaneous change in the value of microscopic property of system in isolated from Thermodynamic Equilibrium When the body is in 1. Mechanical Equilibrium 2. Thermal Equilibrium 3. Chemical Equilibrium 4. Phase Equilibrium

  8. Control volume Any region in space which is separated from its environment by a control surface which may be physical/imaginary Steam out Water in

  9. Concept of Continuum A small volume of the system is compared to the whole system. This volume is bigger than the microscopic level. Allow us to treat property as a point function. Property vary continuously in space.
