The power-specific fuel consumption (PSFC) density formula is typically expressed as the amount of fuel consumed per unit of power output and per unit of time.
Where:
- = Power-Specific Fuel Consumption (units: mass of fuel per unit power per unit time, e.g., kg/kW/hr)
- = Mass flow rate of fuel (units: mass per unit time, e.g., kg/hr)
- = Power output (units: power, e.g., kW)
