Thermodynamics

Course Objectives:

To impart the data of the natural philosophy laws associated principles therefore on modify the scholar to arrange an energy audit of any system that exchange heat and work with the environment.

UNIT – I

Objectives:

The scholar ought to be able to perceive the essential ideas like natural philosophy system, its boundary and connected basic definitions. Distinction between purpose operate and path operate shall be created with regard to energy, work and warmth. Introduction: Basic ideas : System, boundary, encompassing, management volume, Universe, forms of Systems, macroscopic and Microscopic viewpoints, construct of time, natural philosophy Equilibrium, State, Property, Process, Cycle – changeableness – similar – static method, process, Causes of changelessness – Energy in State and in Transition, Types, Work and warmth, purpose and Path operate. ordinal Law of physics – construct of Temperature – Principles of measurement –Reference Points – Const. Volume air thermometer – Scales of Temperature, gas Scale – PMM I

UNIT II

Objectives:

To find out the primary law of physics, that is additionally the energy conservation principle, and may be able to apply to completely different natural philosophy systems. to grasp the construct of equality of temperature and the principle of operation of assorted temperature mensuration devices. to find out the applications of steady flow energy equation to the varied mechanical elements. Joule’s Experiments – 1st law of physics – Corollaries – 1st law applied to a method – applied to a flow system – Steady Flow Energy Equation. PMM-I, choking and free enlargement processes – deviations from gas model – Vander waals equation of state – softness charts – variable specific heats – gas tables.

UNIT – III

Objectives:

To grasp the second law statements and therefore the associated terms and may be able to apply the principles to heat engines. ought to be able to analyse the ideas of oscillation, entropy, handiness and changelessness. ought to be able to perceive the utilization of Maxwells relations and natural philosophy functions. Limitations of the primary Law – Thermal Reservoir, engine, Heat pump, Parameters of performance, Second Law of physics, Kelvin-Planck and Clausius Statements and their Equivalence / Corollaries, PMM of Second kind, Carnot’s principle, oscillation and its specialties, natural philosophy scale of Temperature, Clausius difference, Entropy, Principle of Entropy Increase – Energy Equation, handiness and changelessness – natural philosophy Potentials, Josiah Willard Gibbs and physicist Functions, Maxwell Relations – Elementary Treatment of the Third Law of physics.

UNIT IV

Objectives:

ought to perceive the method of steam formation and its illustration on property diagrams with varied part changes and may be able to calculate the standard of steam when its enlargement in an exceedingly turbine, with the assistance of normal steam tables and charts. Pure Substances, P-V-T- surfaces, T-S and h-s diagrams, Mollier Charts, part Transformations – Triple purpose at vital state properties throughout modification of part, status Fraction – Clausius – Clapeyron Equation Property tables. Mollier charts – varied natural philosophy processes and energy Transfer – Steam measurement.

UNIT – V

Objectives:

Ought to be able to use Psychrometric chart and calculate varied psychrometric properties of air. Mixtures of good Gases – Mole Fraction, Mass friction measuring and meter Analysis – Dalton’s Law of partial pressure, Avogadro’s Laws of additive volumes – Mole fraction , Volume fraction and partial pressure, Equivalent Gas const. And Molecular Internal Energy, Enthalpy, sp. Heats and Entropy of Mixture of good Gases and Vapour, region air – Psychrometric Properties – Dry bulb Temperature, Wet Bulb Temperature, saturation point Temperature, natural philosophy Wet Bulb Temperature, Specific humidness, ratio, saturated Air, vapor pressure, Degree of saturation – adiabatic Saturation , Carrier’s Equation – Psychrometric chart.

UNIT – VI

Objectives:

To grasp the construct of air normal cycles and may be able to calculate the potency and performance parameters of the systems that use these cycles. Power Cycles : Otto, Diesel, twin Combustion cycles, Sterling Cycle, Atkinson Cycle, Ericcson Cycle, Lenoir Cycle – Description and illustration on P–V and T-S diagram, Thermal potency, Mean Effective Pressures on Air normal basis – comparison of Cycles.
Refrigeration Cycles : Brayton and Rankine cycles – Performance analysis – combined cycles, Bell- Coleman cycle, Vapour compression cycle-performance analysis.
