- Gas cycles, Carnot, Otto, Joule (Brayton), Diesel, Dual, Stirling, PV and TS Diagrams, power, efficiency, work
- Engines, C. engines, operation principles, cycles, 2 and 4 strokes, pressure charging, engine trials, indicated and brake power
- Steam and gas turbines, principles, schematic plant layouts, application of appropriate cycles, constructional features, work done, blading efficiency, axial thrust, efficiencies, heat exchanger
- Energy conservation and environmental effects, the environment, total energy conservation in plant, waste heat recovery, overall efficiencies, co-generation plants.
- Steam generating plant and cycles, boiler types, feed systems, feed components, feed water contamination and treatment, boiler efficiencies, evaporators, condensers, heat balance, Dalton’s law of partial pressures.
- Nozzles steam and air flow, critical pressure ratio, nozzle shapes, supersaturation
- HVAC systems, humidity, heating cooling loads, Load line, recycle air, fresh air, plant layout
- Fuels and combustion calculations, chemical equations of combustion, air/fuel ratios, analysis of exhaust gases, gas analysis equipment, solid, liquid and gaseous fuels, calorific values of fuels, preparation of fuels for use, fuel storage, application and use in modern plant.
