Frequently Asked Questions
- What does joule per kilogram measure in this context?
- It measures the specific energy or energy content per unit mass of a fuel or storage medium, helping quantify energy release or storage capacity.
- Why convert joule/kilogram to pound/horsepower/hour?
- To translate specific energy into a mass-based fuel consumption rate, which is useful for evaluating engine efficiency and fuel usage in terms of mechanical power output.
- Can this conversion reflect actual engine efficiency under all conditions?
- No, the conversion uses standard unit definitions and does not consider operational factors like fuel variation or engine condition that impact real efficiency.
Key Terminology
- Joule per kilogram (J/kg)
- SI unit measuring specific energy or specific enthalpy per mass, indicating the energy content of fuel or storage medium per kilogram.
- Pound per horsepower-hour
- Unit expressing the mass of fuel in pounds consumed to produce one horsepower over one hour, indicating engine fuel consumption rate relative to power output.
- Brake Specific Fuel Consumption (BSFC)
- A metric indicating the mass of fuel consumed per unit of power output, commonly reported for piston and automotive engines.
