Formula and methodology
Formula: BSFC = fuel mass flow×3,600/power, expressed in grams per kilowatt-hour.
The conversion compares fuel mass consumed per unit time with delivered power and normalizes the result to one kilowatt-hour.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Fuel mass flow — g/s; minimum 0; maximum 1000000
- Brake power — kW; minimum 1.0E-6; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Fuel mass flow | 0.5 |
| Brake power | 50 |
BSFC = 36 g/kWh.
Assumptions and limits
- Fuel flow is grams per second and delivered power is kilowatts.
- The selected operating point is steady for the conversion.
- Fuel chemistry, transient behavior, emissions, drivetrain losses, and manufacturer ratings are not modeled.
