Gallons Per Hour Fuel Calculator
The Formula
The formula for calculating fuel consumption in gallons per hour is:
Where:
- Fuel Consumption: The rate of fuel usage (in gallons per hour)
- Engine Power: The power output of the engine (in horsepower)
- Fuel Efficiency: The amount of fuel consumed per unit of power per hour
- Fuel Density: The weight of the fuel per gallon
Calculation Steps
- Multiply the engine power by the fuel efficiency to get fuel consumption in pounds per hour
- Divide the result by the fuel density to convert to gallons per hour
Example Calculation
Let's calculate the fuel consumption for an engine with the following specifications:
- Engine Power: 200 HP
- Fuel Efficiency: 0.5 lb/hp-hr
- Fuel Density: 6.7 lb/gal
Fuel Consumption = (200 × 0.5) ÷ 6.7 = 14.93 gal/hr
