Frequently Asked Questions
-
What does gallon (US)/horsepower measure?
-
It expresses the volume of fuel in US gallons consumed per unit of mechanical power in horsepower, often representing specific fuel consumption over time.
-
Why convert gallon (US)/horsepower to CHU per cubic foot?
-
Converting to CHU per cubic foot translates volumetric fuel consumption into an energy density measure, enabling comparison of fuel efficiency with energy content.
-
Where is this conversion typically applied?
-
It is used in marine engineering, industrial engines, power generation, fuel supply chain management, and natural gas energy billing.
-
Does this conversion account for fuel composition variations?
-
No, it assumes consistent fuel properties; practical use should consider variations in fuel quality and energy content.
Key Terminology
-
gallon (US)/horsepower
-
A ratio expressing fuel volume in US gallons consumed per unit mechanical power measured in horsepower.
-
CHU per cubic foot [CHU/ft^3]
-
A unit measuring the amount of energy in CHU contained within one cubic foot of fuel volume.
-
Specific Fuel Consumption
-
Fuel consumed per unit of power output over a specified time, often in gallons per horsepower-hour.
