How to score maximum marks in THERMAL for GATE Examinations?

Here, THERMAL= Basics of Thermodynamics+ Power Engineering + Refrigeration Air conditioning + I.C .Engine

Every time in GATE examinations we get 12 to 15 mark (or more than that also) questions from Thermal. So I am listing the important topics of Thermal

Basics of Thermodynamics:

  • Thermodynamic work calculation of various Non-flow process.( Isothermal , adiabatic polytrophic )
  • Free expansion concept.
  • Clausius inequality Carnot efficiency based problems.
  • Entropy change calculations of an ideal gas through various process.
  • Available energy calculations Increase in unavailability or decrease in availability.
  • Joule Thompson Co-efficient Clausius clapeyron equation concept.

Power Engineering:

  • Brayton Rankine cycle based problems (including compressor turbine efficiency)

Refrigeration Air conditioning:

  • Simple COP Efficiency based problems (2nd law of thermodynamics for cycle based)
  • Vapour Compression Refrigeration System (VCRS) problems (mainly COP Compressor work calculation)
  • Specific humidity Relative humidity formula based problems.

I.C. Engines:

  • Otto cycle Diesel cycle efficiency calculation (Including calorific value, mean effective pressure problems)
  • Comparison among Otto, Diesel Dual cycle (for same compression ratio maximum temperature
