What the Power Machines N5 Question papers cover

• Thermodynamics basics: heat, work, first and second laws, and efficiency concepts.
• Steam boilers and turbines: boiler classifications, safety fittings, turbine operation, impulse and reaction turbines.
• Internal combustion engines: two-stroke and four-stroke engines, cycles, performance factors, and testing.
• Gas turbines: principles of operation, components, applications, and efficiency.
• Hydraulic turbines: Pelton, Francis, and Kaplan turbines, efficiency, and characteristic curves.
• Pumps and compressors: types, operation, performance curves, and industrial uses.
• Refrigeration and air-conditioning: vapour compression cycle, components, COP, and applications.
• Performance testing: efficiency tests, heat balance sheets, and interpreting characteristic curves.
• Safety: safe operation of boilers, turbines, and engines; maintenance procedures; and workplace precautions.

How to approach these papers

• In calculations, always begin with the correct thermodynamic or efficiency formula, substitute with SI units, and show steps clearly.
• For cycle diagrams, sketch neatly (Otto, Diesel, Rankine, Brayton) and label pressure, temperature, and volume axes.
• In turbine and pump questions, describe working principles, show diagrams of flow paths, and include efficiency aspects.
• For internal combustion engines, compare two-stroke vs four-stroke cycles with diagrams and note applications.
• Safety questions should always be answered with both procedure and reason (for example: why safety valves are tested, or why PPE is essential).
